Chemistry · Aldehyde and Ketones: Nature of carbonyl group, nucleophilic addition to >C=O group, relative reactivities of aldehydes and ketones
Compound is:
\( \boldsymbol{C H}_{3} \boldsymbol{B r}+\boldsymbol{M} \boldsymbol{g} \stackrel{\text {Ether}}{\longrightarrow} \boldsymbol{A} \stackrel{\boldsymbol{H C H O}}{\longrightarrow} \) \( \boldsymbol{B} \stackrel{\boldsymbol{H O H}}{\longrightarrow} \boldsymbol{C} \) Compound \( \boldsymbol{C} \) is:
- A. acetic acid
- B. acetaldehyde
- C. ethyl alcohol
- D. formic acid
Step-by-step solution
CH3Br reacts with Mg in ether to form the Grignard reagent CH3MgBr (A). This reacts with formaldehyde (HCHO) to give an alkoxide intermediate (B), which upon hydrolysis (HOH) yields ethanol (C).
