Question 11 Mark
Assertion $(A): (CH_3)_3 C-O-CH_3$ gives $(CH_3)_3 C-I$ and $CH_3OH$ on treatment with $HI.$
Reason $(R):$ The reaction occurs by $S_N1$ mechanism.
Reason $(R):$ The reaction occurs by $S_N1$ mechanism.
Answer
View full question & answer→$(CH_3)_3-C-O-CH_3$ is an ether with two different alkyl groups, of which $(CH_3)_3-C-I,$ tertiary alkyl group, on with hydrogen halide $(HI)$ forms a tertiary halide.
This occurs as the reaction is an $S_N1$ reaction. The reaction involves the formation of a stable carbocation. If the ether has a primary alkyl group, then the reaction follows the $S_N2$ mechanism.
