(a)

Interpretation Introduction

Interpretation:

To predict the major products for the given different reaction and transformations should be identified.

Concept Introduction:

Addition Reaction: It is defined as chemical reaction in which two given molecules combines and forms product. The types of addition reactions are electrophilic addition, nucleophilic addition, free radical additions and cycloadditions. Generally, compounds with carbon-hetero atom bonds favors addition reaction.

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.

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.

Importance of 9-BBN: This reagent selectively reduced for carbon-carbon triple bond converted into bouble bond. The hydrogen ends up bond to the most substituted carbon and the stereo chemistry of the reaction is syn both new bonds are formed on the same face of the alkene.
