The one giving maximum number of isomeric alkenes on dehydrohalogenation reaction is (excluding rearrangement)
Options:
Answer:
C
Solution:
In dehydrohalogenation reactions, the preferred product is that alkene which has the greater number of alkyl groups attached to the doubly bonded carbon atoms. Thus, 2-bromopentane gives pent-2-ene as the major product.
Rest all bromides are having only one type of beta hydrogen, hence, only one possible alkene is formed.
