Give the following conversion acetaldehyde `rarr` alanine.

Answer

`CH_(3)-overset(overset(O)(||))(C)-H+NH_(3)+HCN rarr CH_(3)-underset(underset(NH_(2))(|))(CH)-CN underset(H_(2)O) overset(H_(3)O^(+)//heat) (rarr) CH_(3)- underset(underset(oplusNH_(3) "alanine")(|))overset(overset(H)(|))(C)-COO^(Theta)`.

Explanation

`CH_(3)-overset(overset(O)(||))(C)-H+NH_(3)+HCN rarr CH_(3)-underset(underset(NH_(2))(|))(CH)-CN underset(H_(2)O) overset(H_(3)O^(+)//"heat")(rarr) CH_(2) -underset(underset(oplusNH_(3)"alanine")(|))(overset(overset(H)(|))(C)-COO^(Theta)`.
