Question

$\alpha$-Hydroxypropanoic acid can be prepared from ethanal by following the steps given in the sequence.

• A. Treat with $HCN$ followed by acidic hydrolysis
• B. Treat with $NaHS{O}_4$ followed by reaction with $N{a}_{2}C{O}_3$
• C. Treat with $H_{2}S{O}_4$ followed by hydrolysis
• D. Treat with $K_{2}C{r}_2{O}_7$ in presence of sulphuric acid

Answer 1

The correct option is A Treat with $HCN$ followed by acidic hydrolysis

From the above reaction treatment of Ethanal with $HCN$ followed by acidic hydrolysis gives $\alpha -$Hydroxy propanoic acid.
