Chemistry - Carbonyl compounds Question with Solution | TestHub

Reaction of ${\mathrm{HgSO}}_4/\mathrm{dil}.{\mathrm{H}}_2{\mathrm{SO}}_4$ with alkyne gives addition of water as per markonikoff's rule.

$\mathrm{CH}\equiv \mathrm{CH} \underset{{\mathrm{H}}_2\mathrm{O}}{\overset{{\mathrm{HgSO}}_{4,}{\mathrm{H}}_2{\mathrm{SO}}_4}{\to }} {\mathrm{CH}}_3\mathrm{CHO}$

Hence, by this process preparation of ${\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{CHO}$
Cann't possible.

Hence ${\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{CHO}$ cannot be formed.
