What is the product of the following reaction?

${\mathrm{CH}}_3-\mathrm{C}\equiv \mathrm{CH}+{\mathrm{H}}_2\mathrm{O}\underset{60°\mathrm{C}}{\overset{{\mathrm{HgSO}}_4/\mathrm{dil}.{\mathrm{H}}_2{\mathrm{SO}}_4}{\to }}$

Between formaldehyde and acetaldehyde which gives Cannizzaro's reaction.

What happens when calcium acetate is dry distilled?

An organic compound $\left(\mathrm{A}\right)$ With molecular formula ${\mathrm{C}}_8{\mathrm{H}}_8\mathrm{O}$ forms an orange red precipitate with 2,4 dinitrophenyl hydrazine and gives yellow precipitate on heating with iodine in presence of sodium hydroxide. lt neither reduces Tollen's reagent nor Fehling solution, and it also does not decolourise bromine water or Baeyer's reagent. On drastic oxidation with chromic acid, it gives a carboxylic acid $\mathrm{B}$ having molecular formula ${\mathrm{C}}_7{\mathrm{H}}_6{\mathrm{O}}_2$. Identify the compound $\left(\mathrm{A}\right)$ and $\left(\mathrm{B}\right)$ and explain in detail the reactions involved.

The compound that reduces Tollens' reagent is
