Vedclass · Answer

(A) In the dehydrohalogenation of $2$-bromobutane $(CH_3-CH_2-CH(Br)-CH_3)$ with alcoholic $KOH$,the $Br^{-}$ ion is a good leaving group. According to $Saytzeff$'s rule,the elimination of a $\beta$-hydrogen occurs from the more substituted carbon to form the more stable alkene,$2$-butene $(CH_3-CH=CH-CH_3)$,as the major product. In contrast,alkyl fluorides (option $B$),quaternary ammonium salts (option $C$),and esters (option $D$) typically follow $Hofmann$'s rule,yielding the less substituted alkene ($1$-butene) as the major product due to the poor leaving group ability or steric/electronic factors in their respective transition states.

Which one of the following compounds will give a $Saytzeff$ alkene as the major product in an elimination reaction?
