Vedclass · Answer

(D) $2-$Bromobutane on reaction with sodium ethoxide in ethanol undergoes dehydrohalogenation to give $2-$butene as the major product according to Saytzeff's rule,which states that the more substituted alkene is the preferred product. Thus,the assertion is incorrect because $1-$butene is the minor product. $2-$Butene is more stable than $1-$butene due to greater substitution and hyperconjugation. The reason statement claims $1-$butene is more stable than $2-$butene,which is false. Therefore,both the assertion and the reason are incorrect.
