JEE Main 2026 Apr 4 Shift 2, Chemistry Q15: Stereoisomerism

JEE Main2026Apr 4, Shift 2Chemistry
Q.

The following structures are

  1. A

    enantiomer

  2. B

    Identical molecules

  3. C

    Diastereomers

  4. D

    meso compound

Solution

Examine the substituents on the central carbon: Br, Cl, CH, and Me. But "CH" and "Me" are the same group (methyl).

So the central carbon has two identical substituents and is not a chiral centre. With no stereocentre, the two drawings cannot be enantiomers, diastereomers, or a meso compound — they are simply two drawings of the same molecule.

Identical molecules.
