Aliphatic Compounds
A major class of organic compounds that includes all those with carbon atoms linked in straight or branched open chains. Aliphatic compounds include alkanes,alkenes, or alkynes, or their derivatives.
Example ----alkane, alkene, alkyne, alkadiene, haloalkanes, etc.
Alicyclic Compounds
An organic compound in which carbon atoms are linked to form one or more rings. Aromatic compounds are excluded because of their special properties. In general, alicyclic compounds resemble analogous aliphatic compounds.
Example-------Cyclohexan (C6H12) is alicyclic, as are manyterpenes, such as menthol.

Molality=no. of moles of solute present in 1kg of solvent.............Molarity =no.of moles of solute present in 1 lt.of solution..............

Chandan Kumar 6 years, 5 months ago

No of moles per liter of solution called molarity while no of moles per kg of solvent called molarity

Arham Jain 6 years, 5 months ago

Molarity : The no of moles of solute present in 1 liter of solution. : SI unit is mol / liter. Molality : The no of moles of solute present in 1kg of solvent. : SI unit is mol / kg.

As we know, metals have high tendency to lose electrons.(lower the ionisation energy, higher is the tendency to lose electrons) that's why metals are used in photoelectric cells. Potassium and Caesium have much lower Ionisation enthalpy than that of Lithium . Therefore ,these metals on exposure to light emits electrons easily but lithium doesn't. As a result, K and Cs rather than Li are used in photoelectric cells.

Because of surface tension and intermolecular force of attraction towards its center

Mehak Gautam 6 years, 5 months ago

Mercury drops are spherical because of surface tension. It is the force with which atoms or molecules on the surface of liquid pull each other towards themselves. Hence when small amount of liquid is separated from rest in the form of drop, the whole amount of liquid gets in the most energy efficient shape as sphere due to the attraction of atoms or molecules.

Potassium metal reacts with water by displacing the hydrogen, because it is significantly more reactive. During electrolysis, In aqueous solution the hydrogen from the water will always be liberated in preference to metallic potassium. In the case of sodium, It is not possible to isolate sodium by electrolysis of aqueous solutions of sodium salts because hydrogen ions are more easily reduced than are sodium ions; as a result, hydrogen gas forms at the cathode instead of the desired sodium metal.

Where finding rhe probability of the electron is zero. OKK

Yogita Ingle 6 years, 5 months ago

Electrons are found within the lobes. The plane (or planes) that the orbitals do not fill are called nodes. These are regions in which there is a 0 probability density of finding electrons.
The number of angular nodes = l = 1
The number of radial nodes = (n - l - 1) = 3 - 1 - 1 = 1
Total number of nodes = n - 1 = 3 - 1 = 2

Mixing of s&p orbital is known as hybridisation

Angel James 6 years, 5 months ago

Intermixing of atomic orbitals with different energies gives new orbitals with equal energy and shape this process is known as hybridization.......

B has vaccant orbital and it accept electron so act as lewis acid

Sia ? 6 years, 5 months ago

Acc to Lewis, a substance is an acid only when its octet is not complete.
Also, in BF3 its octet is not complete.
Thus, BF3 act as an acid even it is not having a proton.

When dipolar molecules come closer to non polar molecules then this type of force of attraction is observed

Mohammad Rehan 6 years, 5 months ago

Definition Of Dipole Induced Dipole Forces Induced dipole forces result when an ion or a dipole induces a dipole in an atom or a molecule with no dipole. These are weak forces More About Dipole Induced Dipole Forces An ion-induced dipole attraction is a weak attraction that results when the approach of an ion induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species A dipole-induced dipole attraction is a weak attraction that results when a polar molecule induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species This type of attractive forces operate between the polar molecules having permanent dipole and the molecules lacking permanent dipole Permanent dipole of the polar molecule induces dipole on the electrically neutral molecule by deforming its electronic cloud Thus an induced dipole is developed in the other molecule

Bro . Visit YouTube channels for complete visualisation. Because article ki form me aap understand karne me ,kanhi na kanhi wrong ho sakti for. Don't take it as negative. I am just supporting u to feel the concept of log and antilog in a visualised way whhch can be attained by youtube, Unacademy,vedantu,gradeup.etc

Harsh Mishra 6 years, 5 months ago

For log and Antilog We use there Tables which'll be given in exam as required and you've seen some tables of the same in Practical books or notebooks too.... log has some just 4 or 5 basic formulas and other thing depends on it's value......Well,you don't have to be worry about it as it is just used in science in 11th as probability in math, that is just few topics yeah!!! In 12th you'll understand it better as it is a part of math in 12th which isn't in 11th......That's all.... Hopes, You'd liked the advice......
