|
Answer» e is formed as major product on dehydrohalogenation of 2-Bromo-butaneExplanation:Dehydrohalogenation is an ELIMINATION reaction. 2-Bromo-butane procced through elimination reaction and eliminate HBr. Elimination reaction occurs in the PRESENCE of ALCOHOLIC KOH.Dehydrohalogenation of 2-Bromo-butane in the presence of alcoholic KOH forms 1-Butene and 2-Butene in which 2-Butene is a major product.Major product is decided by Saytzeff's rule. It says that major alkene will be the ONE which is more branched and less branched alkene will be minor product. More branched alkene is major because of hyperconjuction it is more stable. The reaction involved will be- (major) |
