Answer:
Option D
Explanation:
The number of stereoisomers in molecules which are not divisble into two equal halves and have n number of asymmetric C-atoms = 2n
3-methyl-pen-2-ene on reaction with HBr in presence of peroxide forms an addition product i.e, 2-bromo-3-methyl pentane. It has two chiral centres. Therefore 4 stereoisomers are possible.
