Q. 7 P
Question
Reaction of with 2-methylpropene yields 2-bromo-2-methylpropane. What is the structure of the carbocation formed during the reaction? Show the mechanism of the reaction.
Step-by-Step Solution
Verified Answer
The resulting carbocation is ter Butyl carbocation.
1Step 1: Addition reaction
The reaction in which two or more molecules combine to form a single molecule is called an addition reaction.
For example, the addition of hydrogen halide across alkene.
2Step 2: Reaction of with 2-methylpropene
The reaction proceeds via the formation of a tertiary butyl carbonium ion as an intermediate. In the first step, carbocation is formed as an intermediate and in the second step, a bromide ion is added across the carbocation intermediate to give 2-bromo-2-methylpropane.
The reaction mechanism is shown below.
