Question

Which of the following will yield 2-methylpentene upon catalytic hydrogenation?

2-methyl-1-pentene
2-methyl-2-pentene
4-methyl-2-pentene
4-methyl-1-pentene
All of the above

Answer 1

The answer is: 2-methyl-2-pentene and 4-methyl-1-pentene. These two compounds have a double bond in their structures, and catalytic hydrogenation will convert the double bond into a single bond, resulting in the formation of 2-methylpentene.

Answer 2

It can either be one of the choice or all of the above

Answer 3

Apologies for the confusion. You are correct. The correct answer is: all of the above. All four compounds listed will yield 2-methylpentene upon catalytic hydrogenation because they all have a double bond that will be converted into a single bond during the reaction. Therefore, all four compounds will undergo the same hydrogenation reaction to produce 2-methylpentene.
