Question
Chapter 3, Problem 2EQ
Interpretation Introduction
Interpretation:
The leaving group in the given molecule is to be determined in order identify the positively charged and negatively charged fragments produced during mechanism.
Concept Introduction:
Heterolytic cleavage of sigma bond occurs under a variety of conditions. The mechanism of bond cleavage is as shown below,
The arrow in the above mechanism indicates that the sigma electrons form A-B bond are leaving A and becoming the exclusive property of B. Since the fragment A is formally losing one electron, it must become positively charged and B must become negatively charged since it gains an electron.
