Predict the major product 'P' in the sequence of reactions shown in the figure.

Question 49 as printed in the NEET 2025 booklet

  1. A.Structure (1)✓
  2. B.Structure (2)
  3. C.Structure (3)
  4. D.Structure (4)

Solution

HBr with peroxide adds anti-Markovnikov, placing Br on the less substituted ring carbon (C-2) of 1-methylcyclopentene. KCN substitutes Br by –CN, and Na/ethanol reduces the nitrile to . P is 1-methyl-2-(aminomethyl)cyclopentane — structure (1).
