Question
Chapter 14.3, Problem 5P
Interpretation Introduction
Interpretation:
A mechanism for the inter-conversion of 1,2 adduct and 1,4 adduct formed by the reaction of HBr with 1,3-butadiene which are in equilibrium at 40°C is to be proposed.
Concept introduction:
The mechanism of the interconversion required takes place through i) ionization of the halide to yield an allyl carbocation b) resonance delocalization to yield a different allyl carbocation c) attack of bromide ion on both carbocations.
To propose:
A mechanism for the inter-conversion of 1,2 adduct and 1,4 adduct formed by the reaction of HBr with 1,3-butadiene which are in equilibrium at 40°C.
