Question
Identify reagents that can be used to convert acetic anhydride into 3-methyl-3-pentanol.Select answer from the options below1. excess LiAlH4 2. H2OpentanolH2O1. excess CH3CH2MgBr 2. H2O
Solution
The reagents that can be used to convert acetic anhydride into 3-methyl-3-pentanol are:
- excess CH3CH2MgBr
- H2O
Here's the step-by-step process:
-
The Grignard reagent CH3CH2MgBr reacts with acetic anhydride. The Grignard reagent is a strong nucleophile and attacks the carbonyl carbon of the acetic anhydride. This results in the formation of a tertiary alcohol and a molecule of acetic acid.
-
The reaction mixture is then treated with water (H2O) to remove the magnesium salts formed during the reaction. This step also ensures complete conversion of the Grignard reagent to the alcohol.
