A stereospecific reaction is also stereoselective. The initial protonation step could therefore go two different ways, resulting in two different carbocation intermediates. Am.

Energy relations, Regioselective 2-Butene Is reacted with HBr, Major products of above reaction will be :-CH3 - CH = CH - CH3 + HBr ==> CH3 - CHBr - CH2 - CH3 + CH3 - CH2 - CHBr - CH3 • Now both products formed by hydrobromination of 2- Butene are same in structure i.e 2-bromo- Butane • Therefore, When 2-Butene reacts with HBr, it gives 2-bromo-Butane as major product
