Compound(s) that on hydrogenation produce(s) optically inactive compound(s) is(are)
(A)(see structure)
(B)(see structure)✓ Correct
(C)(see structure)
(D)(see structure)✓ Correct
Answer: (B), (D)
Solution
On hydrogenation, alkenes are reduced to alkanes. For the product to be optically inactive, it must either be achiral or a meso compound.
Option (B): The structure has symmetry such that hydrogenation produces an achiral compound. Option (D): Similarly produces an optically inactive product after hydrogenation.
Options (A) and (C) produce chiral products.
Correct answers: (B) and (D).
