Predict the major product 'P' in the following sequence of reactions:

  1. A
    (1) 1-methyl-2-(aminomethyl)cyclopentane
  2. B
    (2) 1-methyl-1-(aminomethyl)cyclopentane
  3. C
    (3) 1-methyl-2-cyanocyclopentane
  4. D
    (4) 1-methyl-1-cyanocyclopentane

Solution & Step-by-step Explanation

1. Step (i): with benzoyl peroxide (anti-Markovnikov addition). Bromine attaches to the less substituted carbon of the double bond. Product: 1-bromo-2-methylcyclopentane.2. Step (ii): (nucleophilic substitution). is replaced by . Product: 1-cyano-2-methylcyclopentane.3. Step (iii): (reduction of nitrile to primary amine). group is reduced to .4. Final product 'P' is 1-methyl-2-(aminomethyl)cyclopentane.
