Vedclass · Answer

(B) $(i)$ The major product of the given reaction is $2$-methylpropene $(CH_2=C(CH_3)_2)$. Sodium ethoxide $(C_2H_5ONa)$ is a strong base,and $t$-butyl chloride is a tertiary $(3^\circ)$ alkyl halide. In the case of tertiary halides,elimination $(E2)$ predominates over substitution $(S_N2)$.
$(ii)$ For the preparation of $t$-butyl ethyl ether,a primary alkyl halide should be reacted with a tertiary alkoxide (Williamson ether synthesis).
$(CH_3)_3C-ONa + C_2H_5-Br 	o (CH_3)_3C-O-C_2H_5 + NaBr$.

The following is not an appropriate reaction for the preparation of $t$-butyl ethyl ether:
$C_2H_5ONa + CH_3-C(CH_3)_2-Cl \to CH_3-C(CH_3)_2-O-C_2H_5$
$(i)$ What would be the major product of this reaction?
$(ii)$ Write a suitable reaction for the preparation of $t$-butyl ethyl ether.
