Chapter 9.7, Problem 22PTS

(a)

Interpretation Introduction

Interpretation:

The selective reagents used to accomplish the given transformation should be draw and identified.

Concept Introduction:

Markovnikov addition: The addition reaction of parotic acids to a different alkene or alkyne, the hydrogen atom of $\text{H-X}$ becomes bonded to the carbon atom that the greatest number of hydrogen atoms in the starting alkene or alkyne.

Anti-Markovnikov addition: These rules describe the regioselectivity (particular place in functional group) where the substituent is bonded to a less substituted carbon, rather than the more substituted carbon. This placed is quite unusual as carbon cations which are commonly formed during alkene or alkyne reactions tend to favor the more substituted carbon.
