Solution
The correct option is D 2-bromo-2-methylpropane Addition of alkene with hydrogen halide is an example of electrophilic addition reaction. Addition of HBr to an unsymmetrical alkene follows markovnikov's rule. This rule states that the negative part of the addendum (adding molecule) gets attached to that C atom which possesses a lesser number of hydrogen atoms. Hence, the major product will be 2-bromo-2-methylpropane.
