Question

Write chemical equation for obtaining primary, secondary, and tertiary alcohols with the help of Grignard's reagent.

Hint:

Grignard reagents react with aldehydes to give secondary alcohols and ketones to give tertiary alcohols.

Answer 1

Step 1: Formation of Alcohols 1. Primary Alcohol \[ R-MgX + HCHO \rightarrow R-CH_2OH \] 2. Secondary Alcohol \[ R-MgX + CH_3CHO \rightarrow R-CH(OH)-CH_3 \] 3. Tertiary Alcohol \[ R-MgX + CH_3COCH_3 \rightarrow R-C(OH)(CH_3)_2 \]
