Answer 2

Option D is the correct answer

Explanation:

• Option (D) 2-Methylbut-2-ene & 3-Methylbut-1-ene​ will give similar product upon hydrogenation in the presence of a catalyst. The product formed in both cases is 3-methylbutane.

• Hydrogenation reaction is a reduction reaction in which the hydrogen atom adds across the double bond.
• It is also referred to as catalytic hydrogenation since it takes place in the presence of a catalyst.
• Corresponding or substituted alkanes are formed upon hydrogenation of alkenes.
