The products in the reaction given below are ' ( ) ' denotes a free radical.

Options

  1. AMeso forms
  2. BRacemic mixture
  3. C(d ) - and (/ )-forms
  4. DCis-trans isomers

Correct answer

B. Racemic mixture

Step-by-step solution

The given reaction is the chain termination step of a free radical substitution reaction. Here, the trigonal planar free radical ( ( C ₂ H ₅- - C H - CH ₃ ) ) gets attacked by ( Cl ⁻ )with equal ease of retention and inversion in configuration. So, the final product is the equimolar mixture of (d ) - and (l )-forms called racemic mixture, which is optically inactive.
