What is the following things happens when an enantiomer undergoes a chimal reaction at a site other than the chiral carbon atom?

Options

A. The reaction occurs with inversion
B. The reaction proceeds with retantion
C. The reaction takes place with complete recemization
D. The reaction proceeds with parital racemization

Answer

B

Explanation

Since the bonds to the chiral `C` are not disturbed, its configuration is unchanged. It is important to note that the `R//S` designation may change if there is a change in the order of priorities of the ligands. Occassionally chirality may disappear.
(i) If the reaction makes two identical ligands at the formerly chiral `C`, the product is achiral.
`underset(ch iral)(CH_(3)CH(OH)CH_(2)CI)overset(reduction)rarrunderset(ach iral)(CH_(3)CH(OH)CH_(3))`
(ii) If the product molecule has a plane or center of symmetry, it is achiral.
