The products in the reaction given below are ' \(\bullet\) ' denotes a free radical.
  1. Meso forms
  2. Racemic mixture
  3. \(d\) - and \(/\)-forms
  4. Cis-trans isomers

Solution


The given reaction is the chain termination step of a free radical substitution reaction. Here, the trigonal planar free radical \(\left(\mathrm{C}_2 \mathrm{H}_5-\stackrel{-}{\mathrm{C}} \mathrm{H}-\mathrm{CH}_3\right)\) gets attacked by \(\mathrm{Cl}^{-}\)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.
