JEE Main 4 April 2026, Shift 2, Chemistry Q65

Question 65 of 75 in this shift, Chemistry question 15 of 25, Section A.

The following structures are [figure: stereocentre C with Br (up), CH3 (hashed, left), Me (down), Cl (wedge, right)] and [figure: stereocentre C with Br (up), Cl (wedge, left), Me (down), CH3 (hashed, right)]

The figure, in words

Two wedge-dash drawings of a carbon bearing Br (up), CH3 on a hashed bond (left in first, right in second), Me (down, plain), Cl on a wedge (right in first, left in second). First: CH3 left hashed, Cl right wedge. Second: Cl left wedge, CH3 right hashed.
