Vedclass · Answer

(A) Dehydrohalogenation follows the $E2$ mechanism,which is favored by the stability of the transition state and the leaving group ability. $1$. The rate of dehydrohalogenation depends on the nature of the leaving group. Iodide $(I^-)$ is a better leaving group than bromide $(Br^-)$ because it is a weaker base. $2$. Tertiary alkyl halides undergo dehydrohalogenation faster than secondary or primary alkyl halides due to the formation of a more stable alkene product (Saytzeff's rule). $3$. Comparing $t$-butyl iodide and $t$-butyl bromide,$t$-butyl iodide reacts faster due to the superior leaving group ability of the iodide ion. Therefore,$t$-butyl iodide is the fastest to undergo dehydrohalogenation.

Which of the following alkyl halides is the fastest to undergo dehydrohalogenation with a base?
