$4-$methoxybenzaldehyde

Vedclass · Answer

(A) The molecular formula $C_8H_8O_2$ corresponds to $p$-methoxybenzaldehyde $(CH_3OC_6H_4CHO)$.$1$. It contains an aldehyde group without $\alpha$-hydrogens,which allows it to undergo the Cannizzaro reaction with conc. $NaOH$ to form $p$-methoxybenzyl alcohol and sodium $p$-methoxybenzoate.$2$. It reacts with acetophenone $(C_6H_5COCH_3)$ in the presence of a base to undergo a cross-aldol condensation,forming a single product because the aldehyde lacks $\alpha$-hydrogens,ensuring it acts only as the electrophile.

$A$ compound of molecular formula $C_8H_8O_2$ reacts with acetophenone to form a single cross-aldol product in the presence of base. The same compound on reaction with conc. $NaOH$ forms benzyl alcohol as one of the products. The structure of the compound is
