The products in the reaction given below are .......' $\bullet$ ' denotes a free radical.
1 Meso forms
2 Racemic mixture
3 $d$-and $I$-forms
4 Cis-trans isomers
Explanation:
(B) : The given reaction is the chain termination step of a free radical substitution reaction. Here, the trigonal planar free radical $\left(\mathrm{C}_{2} \mathrm{H}_{5}-\mathrm{CH}-\mathrm{CH}_{3}\right)$ gets attacked by $\mathrm{Cl}^{-}$ with equal ease of retention and inversion in configuration. So, the final product is the equimolar mixture of $\mathrm{d}$ - and $\ell$ - forms called racemic mixture, which is optically inactive.

The type of isomerism exhibited by
1 Functional isomerism
2 Geometric isomerism only
3 Optical isomerism only
4 Geometric and Optical isomerism
Explanation:
The given compound exhibits optical and geometrical isomerism as it contains chiral carbon atom. It exists in the form of $\mathrm{d}$ and $l$ isomers. The isomer occurs when there is a change in spatial arrangements of ligands. cis and trans are the two terms used for representing the position of identical ligands when they are placed adjacent and opposite.
