Esters

The product of acid hydrolysis of $\mathrm{P}$ and $\mathrm{Q}$ can be distinguished by which of the following:

An ester $\left(\mathrm{A}\right)$ with molecular formula ${\mathrm{C}}_9{\mathrm{H}}_{10}{\mathrm{O}}_2$ was treated with an excess of ${\mathrm{CH}}_3\mathrm{MgBr}$ and the complex so formed was treated with ${\mathrm{H}}_2{\mathrm{SO}}_4$ to give an olefin $\left(\mathrm{B}\right).$ Ozonolysis of $\left(\mathrm{B}\right)$ gave a ketone with molecular formula ${\mathrm{C}}_9{\mathrm{H}}_8\mathrm{O}$ which shows $+\mathrm{ve}$ iodoform test. The structure of $\left(\mathrm{A}\right)$ is:

Which of the following esters cannot undergo Claisen self-condensation?

Which one of the following esters cannot undergo Claisen self-condensation?

An ester is boiled with $\mathrm{KOH}.$ The product is cooled and acidified with concentrated $\mathrm{HCl}.$ A white crystalline acid separates. The ester is:

When esters are hydrolysed, the product gives hydrogen ions. The product which gives hydrogen ion is:

Self-condensation of two moles of ethyl acetate in the presence of sodiumethoxide after acidification yields:

Hydrolysis of an ester gives a carboxylic acid, which on Kolbe's electrolysis, yields ethane. The ester is:

The hydrolsis of an ester gives a carboxylic acid, which on Kolbe's electrolysis yields ethane. The ester is

An ester is boiled with $\mathrm{KOH}$. When the product is cooled and acidified with concentrated $\mathrm{HCl}$, a white crystalline acid separates. The ester is
