Vedclass · Answer

(B) Step $1$: The reaction of $2$-bromopentane with alcoholic $KOH$ is a dehydrohalogenation reaction (an elimination reaction).Step $2$: According to $Saytzeff's$ rule, in elimination reactions, the more substituted alkene is the major product.Step $3$: The reaction is: $CH_3-CH(Br)-CH_2-CH_2-CH_3 + KOH (alc.) \rightarrow CH_3-CH=CH-CH_2-CH_3 + KBr + H_2O$.Step $4$: $Pent-2-ene$ is more substituted than $Pent-1-ene$, hence it is the major product.
