Vedclass · Answer

(B) The reaction of $tert$-butyl bromide $((CH_3)_3CBr)$ with silver fluoride $(AgF)$ is a Swarts reaction,which is used for the synthesis of alkyl fluorides.However,$tert$-butyl bromide is a tertiary alkyl halide. When heated with $AgF$,it undergoes an $E1$ elimination reaction rather than a nucleophilic substitution ($S_N1$ or $S_N2$) because the tertiary carbocation is highly stable and the fluoride ion acts as a base.The major product formed is $2$-methylpropene (isobutylene) due to the elimination of $HBr$.

When $tert$-butyl bromide is heated with silver fluoride,the major product obtained is:
