NEET Chemistry Elimination Reactions MCQ Question
Consider a diagram of a dehydrohalogenation reaction involving 2-bromopentane. Which alkene is formed as the major product according to Zaitsev's rule?
Pent-2-ene
Pent-1-ene
2-Methylbut-2-ene
3-Methylbut-1-ene
Correct Answer
Detailed Explanation
According to Zaitsev's rule, in dehydrohalogenation reactions, the preferred product is the alkene with the greater number of alkyl groups attached to the doubly bonded carbon atoms. Therefore, pent-2-ene is the major product of the elimination reaction of 2-bromopentane.
