Which of the following may exist in enantiomorphs

Options

A. `CH_(3) - overset(CH_(3))overset(|)( C) H - COOH`
B. `CH_(2) = CH CH_(2) CH_(2) CH_(3)`
C. `CH_(3) - overset(NH_(2))overset(|)( C) H - CH_(3)`
D. `CH_(3) - CH_(2) - overset(NH_(2))overset(|)( C)H - CH_(3)`

Answer

D

Explanation

`CH_(3) - CH_(2) - overset(NH_(2))overset(|) underset(H)underset(|) (C^(**))- CH_(3)`
Chiral centre is present. Hence, it exists as optical isomers or enantiomorphs
