JEE Main Chemistry question

Which of the following exists as a pair of mirror-image (enantiomeric) isomers?

(A)C₆H₅–CH(NH₂)–CH₃ (1-phenylethylamine)Correct
(B)C₆H₅–C(NH₂)(CH₃)₂ (2-phenylpropan-2-amine — two identical methyl groups, not chiral)
(C)C₆H₅–CO–CH₃ (acetophenone — a planar carbonyl, no stereocentre)
(D)CH₃–C₆H₄–NH₂ (a toluidine — substituents directly on the ring, no stereocentre)

Answer: (A)

Solution

1-Phenylethylamine's benzylic carbon bears four different groups (–C₆H₅, –NH₂, –CH₃, –H), making it a genuine stereocentre
