This is a Long Answer Type Questions as classified in NCERT Exemplar
A contrast is drawn in thermodynamics between extensive and intense qualities. An extensive property is one whose value is proportional to the amount or size of matter in the system. Extensive properties include mass, volume, internal energy, enthalpy, and heat capacity, to name a few.
Properties that are independent of the amount or size of matter present are known.
As though they were intensive properties Temperature, density, and pressure, for example, are intense properties. A molar property? m, is the value of an extensive property of the system for 1 mol of the sub

Resonating structures of phenoxide are-
In structure I and V negative charge is on E.N. Oxygen, in other cases, it is on Less E.N Carbon hence they contribute less towards stability. And the negative charge is localized.
Resonating structures of carboxylic acid-
Both the structures have –ve charge on oxygen and electron are delocalised too hence, the carboxylic acid is more stable and acidic than phenol.

1. Cyclohexanone forms cyanohydrin in good yield because the ketonic group has very less steric hindrance at both the ortho position but 2,2,6 tri methyl cyclohexanone have high steric hindrance which reduces the attack from CN nucleophile.

1. When 1- phenyl ethane is oxidized with a strong oxidizing agent like KMnO4, it forms a benzoic acid ion.
4. When benzene is mixed with benzoyl chloride in presence of Anhyd.AlCl3 to give benzophenone.
5. When 4-oxocyclohexanecarbeldehyde is treated with tollens reagent it gets oxidized to carboxylate anion as it is aldehyde it reduces tollens reagent.
6. When 2-formyl benzoic acid is treated with NaCN it produces 2-[1-hydroxycyanom

This is a assertion and reason answer type question as classified in NCERT Exemplar
(i) Statements A and R both are correct and R is the correct explanation of A. Since, metals like Pd and Pt adsorbs a large volume of hydrogen, hence, these are used as a storage media for it.

1. Acetylation refers to the process of introducing an acetyl group (resulting in an acetoxy group) into a compound, namely the substitution of an acetyl group for an active hydrogen atom. A reaction involving the replacement of the hydrogen atom of a hydroxyl group with an acetyl group (CH3CO) yields a specific ester, the acetate. Acetic anhydride is commonly used as an acetylating agent reacting with free hydroxyl groups., this reaction is usually carried out in the presence of base like pyridine.
2. Aldeydes having no α-H undergo the disproportion reaction in the presence of Strong alkali, it is a chemical reacti
