Vedclass · Answer

(A) The dehydrobromination of $2$-bromobutane $(CH_3-CHBr-CH_2-CH_3)$ follows $Saytzeff's$ rule.According to this rule,the more substituted alkene is the major product.$2$-bromobutane can undergo elimination to form either $1$-butene $(CH_2=CH-CH_2-CH_3)$ or $2$-butene $(CH_3-CH=CH-CH_3)$.$2$-butene is a disubstituted alkene,while $1$-butene is a monosubstituted alkene.Since $2$-butene is more stable due to hyperconjugation and inductive effects,it is formed as the major product.

The dehydrobromination of $2$-bromobutane results in the formation of which of the following?
