`underset("Ketone")underset("Symmetrical")((A)) overset(LiAlH_(4))(to)(B)overset(H^o+)underset(Delta)(to)` Diastereomers
Reactent (A) is :

underset("Ketone")underset("Symmetrical")((A))overset(LiAlH_(4))to(B)underset(Delta)overset(H^(o+))to"Diastereomers" Reactent (A) is :

(A)underset("dil."H_(2)SO_(4))overset(HgSO_(4))(to)(B)overset(LiAlH_(4))(to) underset("recemic mixture")((C)) therefore reactant (A) is :
