An organic compound (A) with the molecular formula $\displaystyle \mathrm{C}_{9} \mathrm{H}_{10} \mathrm{O}$ forms $\displaystyle 2$, $\displaystyle 4$-DNP derivative, reduces Fehling solution and undergoes Cannizzaro reaction. On vigorous oxidation, it gives $\displaystyle 1$, $\displaystyle 2$-benzene dicarboxylic acid.

Identify the compound (A) and write its IUPAC name.

Write the reaction of compound (A) with

$\displaystyle 2$, $\displaystyle 4$-Dinitrophenyl hydrazine and

Fehling solution

Write the equation of compound (A) when it undergoes Cannizzaro reaction. $\displaystyle \mathbf{2}+\mathbf{2}+\mathbf{1}$

Account for the following :

The alpha ( $\displaystyle \alpha$ )-hydrogens of aldehydes and ketones are acidic in nature.

Oxidation of aldehydes is easier than ketones.

Arrange the following in :

Decreasing reactivity towards nucleophilic addition reaction propanal, acetone, benzaldehyde.

Increasing order of boiling point : Propane, Ethanol, Dimethylether, Propanal

Give simple chemical test to distinguish between Benzoic acid and Benzaldehyde.
