Question

Given below are two statements:

Statement I : \(CH_3 - O - CH_2 -Cl\)  will undergo

\(S_N 1\) reaction though it is a primary halide.

Statement II : \(CH_3 - \overset{\overset{CH_3}{|}}{\underset{\underset{CH_3}{|}}{C}} - CH_2 - Cl\)  will not undergo \(S_N 2\) reaction very easily through it is a primary halide.

In the light of the above statements, choose the most appropriate answer from the options given below:

(1) Statement I is incorrect but Statement II is correct.

(2) Both Statement I and Statement II are incorrect

(3) Statement I is correct but Statement II is incorrect

(4) Both Statement I and Statement II are correct.

Answer 1

Correct option is: (4) Both Statement I and Statement II are correct.

\(CH_3 - O - CH_2 - Cl \) will undergo \(S_N1\) mechanism because \(CH_3 - O - \overset{\overset{+}{}}{C}H_2\)  is highly stable.

\(H_3 - \overset{\overset{CH_3}{|}}{\underset{\underset{CH_3}{|}}{C}} - CH_2 - Cl\)  (Neopentyl chloride) will undergo \(S_N 2\) mechanism at a slow rate because it’s sterically crowded.
