What is the major product P formed from the reaction of the given alkene with concentrated HBr?
Understand the Problem
The image shows an organic chemistry reaction where an alkene reacts with concentrated HBr to produce a major product P. We need to determine the structure of the major product, taking into account the reaction mechanisms and potential rearrangements.
Answer
The major product is 2-bromo-2-methylpropanoic acid methyl ester.
The major product P formed from the reaction of the given alkene with concentrated HBr is 2-bromo-2-methylpropanoic acid methyl ester.
Answer for screen readers
The major product P formed from the reaction of the given alkene with concentrated HBr is 2-bromo-2-methylpropanoic acid methyl ester.
More Information
The reaction proceeds via Markovnikov's rule, where the hydrogen atom of HBr attaches to the carbon with more hydrogen atoms, and the bromine atom attaches to the carbon with fewer hydrogen atoms. Also, with concentrated HBr, the alcohol (OH) will be replaced by a bromine atom.
Tips
A common mistake is forgetting the Markovnikov's rule for the addition of HBr to the alkene.
