Question

In $S_{N^1}$ reaction, . the recimisation takes place due to

• A. inversion of configuration
• B. retention of configuration
• C. conversion of configuration
• D. both (A) and (B)

Answer 1

Answer: (D)

$S_{N^1}$ reaction involves formation of carbocation which are planar ($s{p}^2$-hybridised) and thus can be attacked on either side of carbon.
Primary amines react with $CHC{I}_3$ in alcoholic KOH to form isocyanides $(Carbylaminereaction)$.
