B. `CH_3 - CH_2 - CH_2 - NH_2`
C. `CH_3 - CO - COOH`
D. `CH_3 - underset(OH)underset(|)(CH)-COOH`

Answer

D

Explanation

`underset("Ethanal")(CH_3CHO)+HCN rarr underset("Cynohydrin")underset("(A)")(CH_3C-underset(H)underset(|)overset(OH)overset(|)C-CN) overset(H_3O^(+))to underset("Lactic acid")(CH_3-underset(H)underset(|)overset(OH)overset(|)C-COOH)`
