Question

Quizplus · Accepted Answer

The reaction involves the addition of HBr to 2-methylpropene. This is an example of electrophilic addition reaction. The major product obtained will be the one where the bromine atom is attached to the carbon that has the most number of hydrogen atoms. In this case, addition of HBr to 2-methylpropene can give two products: 2-bromo-2-methylpropane (I) and 2-bromo-3-methylbutane (II). But II will have more number of hydrogen atoms on the carbon to which bromine is attached compared to I. Therefore, II will be the major product obtained from the reaction.
