Kinetic Vs Thermodynamic Product - 1,2 vs 1,4 Addition

This organic chemistry video tutorial provides a basic introduction into the 1,2 addition reaction and the 1,4 addition of HBr to 1,3-butadiene.  The kinetic product is the major product that forms faster at a low temperature.  The thermodynamic product is the most stable alkene that forms as the major product at high temperatures.
