    One of the most common ways to allow both acetaldehyde and acetone to react with Tollen’s reagent. A silver mirror is formed when acetaldehyde reacts with Tollen’s reagent. No such compound is formed on reaction of the agent with acetone. When acetone is subject to iodoform test, a precipitate is formed. There will be no such reaction when acetaldehyde is subject to iodoform test. Fehling’s reagent and chromic acid test can help in the identification of an acetaldehyde

    More importantly, why? The reason is the . KCl dissociates into ions which affect like boiling point elevation and freezing point depression. The experimental factor for KCl is reported to be 1.85 (expected value from theory, if the salt was fully dissociated, would be 2), while the factor for solutes like sugar which don’t dissociate into separate ions is essentially 1.0. So the effect on the elevation of boiling point is proportional to the , and for KCl is almost double that of sugar, yes.

    Thermoplastic: Thermoplastics pellets soften when heated and become more fluid as additional heat is applied. The curing process is completely reversible as no chemical bonding takes place. This characteristic allows thermoplastics to be remolded and recycled without negatively affecting the material’s physical properties. There are multiple thermoplastic resins that offer various performance benefits, but most materials commonly offer high strength, shrink-resistance and easy bendability. Depending on the resin, thermoplastics can serve low-stress applications such as plastic bags or high-stress mechanical parts. Pros: Highly recyclable Aesthetically-superior finishes High-impact resistance Remolding/reshaping capabilities Chemical resistant Hard crystalline or rubbery surface options Eco-friendly manufacturing Cons: Generally more expensive than thermoset Can melt if heated

    The primary physical difference is that thermoplastics can be remelted back into a liquid, whereas thermoset plastics always remain in a permanent solid state. Think of thermoplastics as butter – butter can be melted and cooled multiple times to form various shapes. Thermoset is similar to bread in that once the final state is achieved, any additional heat would lead to charring. Thermoset plastic: Thermoset plastics contain polymers that cross-link together during the curing process to form an irreversible chemical bond. The cross-linking process eliminates the risk of the product remelting when heat is applied, making thermosets ideal for high-heat applications such as electronics and appliances. Thermoset plastics significantly improve the material’s mechanical properties, providing enhances chemical resistance, heat resistance and structural integrity. Thermoset plastics are often used for sealed products due to their resistance to deformation. Pros : More resistant to high temperatures than thermoplastics Highly flexible design Thick to thin wall capabilities Excellent aesthetic appearance High levels of dimensional stability Cost-effective Cons: Cannot be recycled More difficult to surface finish Cannot be remolded or reshaped

    HCl is less reactive with alcohols since the bond between H and Cl is a bit stronger than HBr and HI. Hence its reaction with alcohols need a catalyst ZnCl2, which helps in breaking the bond between H and Cl. Sometimes, as with primary alcohols, heating is required to achieve this along with ZnCl2.

    Hey Priya in Chlorobenzne there's a double bond character in c-cl bond due to resonance in benzene so it is more stronger and in Benzyl chloride the chlorine Atom is not directly attached to benzene further it is attached to alkyl group so it is easy to break it rather than breaking the c-cl bond in benzene so Naoh reacts easily with it.

    Peptization: Peptization may be defined as the process of converting a precipitate  into colloidal sol by shaking it with  dispersion medium with a small amount of electrolyte. The electrolyte used for this purpose is called peptizing agent.   when  ferric chloride is added  to ferric hydroxide precipitate, the precipitate of hydroxide changes to sol by adsorbing ferric ions.  Fe3+  is absorbed on Fe(OH)3  and breaks into colloids.

    N-N single bond is weaker than P-P bond due to smaller size of N as compared to P. Smaller size of N leads to smaller N-N bond length. As a result, the lone pair of electrons on the both the N atoms repel each other leading to unstability or weakening of N-N bond. Because of larger size of P atom, P-P bond length is more and lone pair-lone pair repulsion between P atoms is less which makes the P-P bond stronger than N-N bond.

    Ammonia is a stronger base than phosphine because in ammonia the central atom Nitrogen is smaller hence electron density is concentrated with in smaller range and easily available. Whereas in the case of phosphine the size of phosphorous is large electron cloud is distributed in large area and not easily available.

    Peptide linkage: a peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction) and usually, occurs between amino acid. Peptide linkage is responsible for the primary structure of protein.
