Interpretation Introduction

Interpretation:

The major product for the given reaction should be identified.

Concept introduction:

Bromination:

Alcohols brominated by using ${\text{PBr}}_{\text{3}}$ which provides corresponding brominated products.

Oxidation: Alcohols undergoing oxidation by using oxidizing agent like PCC (Pyridinium Chlorochromate) in dichloromethane which provides aldehyde.

Alcohols undergoing oxidation by using oxidizing agent like Na₂Cr₂O₇ which provides aldehyde or carboxylic acid.

9-BBN (9-Borabicyclo [3.3.1] nonane) or diborane is used for the hydroboration of alkene. Boron addition to the double bond and subsequent oxidation of the new formed borane yields anti-Markovnikov alcohols

Reduction: Aldehydes or ketones undergoing reduction by using reducing agent like LAH or ${\text{NaBH}}_{\text{4}}$ which provides alcohol.

Lindlar catalyst: it is a heterogeneous catalyst that consists of palladium deposited on calcium carbonate. Lindlar catalyst is used for the hydrogenation process of alkynes to alkenes.

Potassium tert-butoxide is a strong base, which used for the abstraction of acidic hydrogen from the molecule.

Alcohols is protected by using variety of reaction for example, Alcohols can be protected by treating with tosyl chloride in presence of base. Similarly it can be protected by using TMSCl in presence of base
