Chapter 11, Problem 11.2YT

Interpretation Introduction

Interpretation:

The curved arrows and the name of each elementary step in addition of $\text{HBr}$ across the double bonds in cyclohexene are to be labelled.

Concept introduction:

Electrophilic addition reaction is an addition reaction in which the double bond attacks an electrophile and the new addition of one or more groups across multiple bonds. In this reaction, $\text{C=C}$ double bond breaks and a new single bond form. In electrophilic addition reaction of alkene, the electrophile $\text{HBr}$ is attached across the $\text{C=C}$ double bonds. The addition of hydrogen halide to alkene produces alkyl halide as a product. In an elementary step, electrons tend to flow from an electron-rich ion to the electron-poor ion. The electron-poor group has a positive charge and highly electronegative atoms have a negative charge.
