What is the expected product from the reaction of 2,3-dimethyl-1-hexene with hydrogen gas?
A) 2,2-dimethylhexane
B) 2,3-dimethylhexane
C) 3,3-dimethylhexane
D) 2-methylheptane
E) 2,3-dimethyl-2-hexene

Question

Quizplus · Accepted Answer

The reaction between 2,3-dimethyl-1-hexene and hydrogen gas is a hydrogenation reaction, which adds hydrogen to the double bond to form a single bond. The hydrogen atoms add to the carbons of the double bond in a syn-addition manner, which means the two hydrogen atoms will add to the same side of the double bond. This results in the formation of 2,3-dimethylhexane, which is option B.
