1.

Which of the following regarding 1,2 or 1,4-conjugate addition of HBr to 1,3-butadiene is false?

Answer»

the kinetic product 3-bromo-1-butane, ARISES from the most stable carbocation intermediate
the thermodynamic product, 1-bromo-2-butene, is the most stable product
the kinetic product is favoured by carrying out the reaction at high temperature
formation of TWO products arises from a common RESONANCE stabilized carbocation intermediate

SOLUTION :The thermodynamic product is favoured by carrying out the reaction at high temperature
