In an elimination reaction involving 2-bromopentane, which of the following is the major product based on the number of alkyl groups attached to the doubly bonded carbon atoms?
Pent-2-ene
Pent-1-ene
2-Methylbut-1-ene
3-Methylbut-1-ene
Correct Answer
Detailed Explanation
According to Zaitsev's rule, the preferred product in dehydrohalogenation reactions is the alkene with the greater number of alkyl groups attached to the doubly bonded carbon atoms. Thus, 2-bromopentane gives pent-2-ene as the major product.
