$CH_3-CH(OH)-CH_2CHO$

Vedclass · Answer

(D) Step $1$: Acetylene $(HC \equiv CH)$ undergoes hydration in the presence of $30\% \ H_2SO_4$ and $HgSO_4$ to form vinyl alcohol,which tautomerizes to acetaldehyde $(CH_3CHO)$. Thus,$A = CH_3CHO$.Step $2$: Acetaldehyde contains $\alpha$-hydrogen atoms,so it undergoes aldol condensation in the presence of dilute $NaOH$ to form $3$-hydroxybutanal $(CH_3-CH(OH)-CH_2CHO)$. Thus,$B = CH_3-CH(OH)-CH_2CHO$.

Predict the product $B$ in the sequence of reaction:
$HC \equiv CH$ $\xrightarrow{30\% \ H_2SO_4, HgSO_4} A$ $\xrightarrow{dil. \ NaOH} B$
