Which of the following is the expected product from the reaction of 2,3-dimethyl-1-heptene with hydrogen gas?
A) 2,2-dimethylheptane
B) 2,3-dimethylheptane
C) 3,3-dimethylheptane
D) 2-methyloctane
E) 2,3-dimethyl-2-heptene

Question

Quizplus · Accepted Answer

The reaction of an alkene with hydrogen gas in the presence of a catalyst (hydrogenation) results in the addition of hydrogen atoms to the double bond, converting the alkene into an alkane. The double bond in 2,3-dimethyl-1-heptene will be hydrogenated to give 2,3-dimethylheptane, as the hydrogenation does not change the position of the methyl groups or the length of the carbon chain.
