Question

Reaction of acetaldehyde with HCN followed by hydrolysis gives a compound which shows (A) optical isomerism (B) geometrical isomerism (C) metamerism (D) tautomerism

Tardigrade Admin · Accepted Answer

All the four valencies of C* (chiral atom) in lactic acid are attached with different groups or atoms hence, it is optically active. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/98e0df66e455070ed0e6856f1166eea0-.png" />
