Concept explainers
a.
Interpretation:
Write the three different sets of reagents (each set containing of a carbonyl compound and Grignard reagent that would be used to prepare each of the following tertiary alcohols.
Concept introduction:
So many number of reactions are involved in the Carbonyl group. The carbonyl group is electrophilic nature, therefore it undergoes nucleophilic addition reactions.
For example carbonyl group reacts with Grignard reagent, it undergoes nucleophilic addition reactions and form unstable tetrahedral intermediate by the elimination of leaving group.
Addition of hydrogen ion to the carbonyl carbon to form alkoxide ion. By the protonation of alkoxide ion forms alcohol.
