What is the kinetic product obtained from the addition of 1 equivalent of HBr to 1,3-butadiene?
A)3-Bromo-1-butene
B)1-Bromo-2-butene
C)2-Bromo-2-butene
D)2-Bromo-1-butene

The kinetic product is formed faster and is usually the result of the more stable carbocation intermediate. In the case of 1,3-butadiene reacting with HBr, the addition of HBr across the 1,2-position leads to the formation of 3-Bromo-1-butene, which is the kinetic product.
