Interpretation Introduction

(a)

Interpretation:

The preparation of the given compound from ethyl bromide as a starting material is to be predicted.

Concept introduction:

Grignard reagents are organometallic compounds which are prepared using alkyl halides in the presence of magnesium metal in dry ether. These reagents act as strong nucleophiles and bases. Grignard reagents react with carbonyl compounds to form alcohol.
