Consider the reaction : Briefly explain the choice of major product. |
| Answer» Solution : Initial reaction of the ALKENE with `H_(3)O^(+)` can form two carbocations. The more stable BENZYLIC tertiary carbocation (shown in the above mechanism) is formed in preference to the less stable PRIMARY carbocation. This is the rate deter MINING step, and thus controls the product DISTRIBUTION. Formation of the more stable carbocation is the mechanistic basis for Markovnikov.s rule. | |
