It is the process to synthesize alkylhalide from alcohol using ZnCl₂.

The reaction can be written as:
                               Anhyd ZnCl₂
R --- OH + H---X     ========>>   RX + H₂O

The reactivity order of  in the above reaction is : HI > HBr > HCl > HF

Reactivity order of alcohols =  3⁰ > 2⁰ > 1⁰ > MeOH

2⁰ and 3⁰ alcohols undergo SN₁ mechanism, whereas 1⁰ and MeOH undergo SN₂ mechanism. Concentrated HCl + anhy. ZnCl₂ is known as lucas reagent. In Groove's process, ZnCl₂ is used to weaken C-OH bond. In case of 3⁰ alcohol, ZnCl₂ is not required.

Example =                  Anhyd ZnCl₂
C₂H₅OH + HCl    ===========>>  C₂H₅Cl + H₂O

Edla was kind and good natured. She had more convincing power than her father and was able to persuade the peddler to accept the invitation. She was pained by the plight of the peddler and continued to treat him well even after the truth about his identity was revealed. Her behaviour reflects maturity and grace.

Varsha Dahiya 5 years, 6 months ago

Edla has positive values and a strong sense of observation. She brings the peddler home despite judging her guest to be a tramp. Her sympathetic attitude makes her persuade her father to let the guest stay bcuz they had promised him" Christmas cheer " . It is bcuz of her concern and compassion that the peddler redeems himself from dishonesty and undergoes a thorough transformation.

2. Summers in Alabama had always been hot. My childhood memories are filled with days spent floating in the pond, sitting on the porch swing, lying sprawled in front of any source of moving air, trying in vain to get, and stay, cool. But when I walked out of the airport, already tired from a three-hour flight that had been delayed by over half an hour, laden with suitcases and dressed for an overly air-conditioned office climate, the heat came over me like a blanket. An old, unwashed woolen blanket that had been soaked in water, allowed to dry crumpled on the floor, then resoaked and thrown at me in all of its mildewed glory. The short walk to the car-rental agency felt like a trek through the jungle; by the time I got to my rental, my shirt was soaked through in patches, my hair was limp and sticky, and my mood was foul. 3. During the hour-long drive home, I had plenty of time to think. About why I had left, about all the things I had chosen to leave behind, about the life I had built for myself far away from this world of heat and poverty and depression. Lost in my thoughts, I found myself driving up the gravel road leading to my childhood home before realized where I was. The clapboard house looked the same as it had when I had left ten years earlier, save for a slight accumulation of the junk common to front yards in this part of the world. The old tire swing still hung askew from the hickory tree, half the ropes worn away from constant use. On the porch sat a rocker that had once been my grandmother's and a watering can that looked almost as old. Parking off to the side, I grabbed my bags anxiously, trying to calm my nerves, and braced myself. 4. No one ever used the front door to the house. I remembered that, of course, and walked instead to a side door that opened onto the kitchen. The door itself was propped open to allow for whatever breeze might meander by, the screen door shut to keep out the mosquitoes, giving me a view of the room. There was the kitchen table, covered in dents and scratches but polished to a high sheen; behind and to the right, the pantry, no doubt stocked full of the jars of preserves that my mother would have been making allsummer; and straight' ahead, my mother standing at the sink. She had aged during the years of my absence. I could see it in the way she stood, slightly hunched over the sink, and in the color of her hair, pulled back as always. She had to have heard me. Coming - gravel rods announce visitors from miles away – but she showed no sign that she knew I was standing there in the doorway, debating whether or not to knock. 5. Mother? It’s me. I’m here.” Her back straightened as the replied, though she never turned or left the sink. “Come on in, and be sure to close the screen door behind you. It is been a bad year for bugs. 6. I opened the door and stepped back in time. When I had announced my plan to go away for school, she had asked me how I thought I was going to pay for it. When the holidays came around, and I told her I wasn't going to be able to come home, she didn't ask why, and when I stopped calling on a regular basis, she didn't then either. How many nights I had spent, hating her for making those decisions so hard for me? Already I could feel the anger rising, that she could act so unconcerned at my arrival, standing at the sink shelling peas. Her only daughter whom she hadn't seen for a decade. 7. As I approached the sink, ready to demand an explanation, I saw that her hands were shaking, the peas falling into the sink as much as the bowl. She looked so much older, aged even more than I had thought, in the same faded dress she'd probably worn for five years. It suddenly hit me that all that time, she hadn't called not because she didn't care, but because she did. She had never been able to leave, but I had, and she understood that I needed to strike out on my own, far from here. Now here I was, in my fancy city clothes, with my college degree and impressive job, and she didn't know what to say. I bridged the gap the only way I knew how: I rolled up my sleeves, and started to help with the peas. (A) On the basis of your understanding of this passage answer the following questions with the help of given options: (i) The narrator considers the weather in Alabama during the summer time to be: 2 (a) Humid and extremely hot. (b) Unbearably hot and miserable. (c) Cool and Breezy. (d) Pleasantly familiar.

Buddhism

Jainism

Rebirth is one of the principal beliefs in Buddhism. It is thought that the endless cycle of birth and re-birth can only be broken by attaining <i>Nirvana </i>(Enlightenment) Jainism believes that the circle of rebirths and deaths will continue due to good or bad deeds until liberation is achieved
Scriptures include <i>Tripitaka</i>, which is a vast text consisting of 3 sections: the Discipline, the Discourse and the Commentaries.  Jain religious texts are called <i>Agamas</i>
The principal teaching of Buddhism is that life is suffering and to escape suffering (end cause of desire) one needs to dispel ignorance by realizing the Four Noble Truths and practising the Eightfold Path Jainism lays emphasis on the respect of all living beings. Liberation from the cycle of rebirths is attained by taking the Five Vows and following the principles of the Three Jewels
Sin is not a concept in Buddhism Sin is defined as harm to others
Buddhism is divided into two major sects upon the death of Gautama Buddha. They are the Mahayana and the Theravada  Svetambara and Digambara are the two major sects of Jainism
According to some texts in Buddhism, there are beings in heaven but they are bound by “<i>samsara”</i>. They suffer less bu they ave, not yet achieved salvation Deities in Jainism are known as <i>“Titrtheneakas”. </i> But they are not worshipped in the conventional sense as they are regarded as wise teachers whose teachings

The end of 2nd world war not only crippled the European nations like Germany , Italy and Austria. But also weakened victorious nations like Britain and France . They had to face acute shortage of basic necessities of life. The end of war saw two powers ( USA nd USSR) emerging as world powers. Both have different ideologies. USA was supporter of capitistic order and promotes democracy while USSR advocates socialist order. The intense rivalry,clash of ambitious , apposing ideologies and acute difference gave rise to what was called 'cold war' . It was rather "a state of uneasy peace" . Both side tries to impose their political and economic system allover the world. The USA and USSR weren't in state of armed conflicts with each other. It was an era of political or diplomatic conflict. The two great made all possible efforts to weaken the opposite side.

Science is the study of the natural world by collecting data through a systematic process called the scientific method. And technology is where we apply science to create devices that can solve problems and do tasks. Technology is literally the application of science. So, it really is impossible to separate the two. Improved technology used for harvesting food, coupled with the technology of improved sanitation, has accelerated the growth of the human population. A larger human population increases the impact on the environment and its resources, many of which are limited and non renewable.
