The reaction between an acid and an alcohol yields:

When chloroform is hydrolysed with $KOH$,the final product is:

Statement-$I$: Most carboxylic acids exist as dimers in vapour phase or in aprotic solvents due to intermolecular hydrogen bonding.
Statement-$II$: Higher carboxylic acids are practically insoluble in water due to the increased hydrophobic interaction of the hydrocarbon part.

Which among the following is $NOT$ a dicarboxylic acid?

The increasing order of the acidity of the $\alpha$-hydrogen of the following compounds is:

The $OH$ group of an alcohol or the $-COOH$ group of a carboxylic acid can be replaced by $-Cl$ using:
