### Question 3
**Propose suitable reagent(s) to accomplish the following transformations. (4 points each)**
#### Given Reactions:
**(a) Transformation:**
- **Starting Compound:** A ketone with a butyl side chain.
- **Target Compound:** An ester with a hydroxy group on the gamma carbon.
*Proposed Reagents and Conditions:*
- Use *Sodium borohydride (NaBH4)* in *methanol (CH3OH)* to reduce the ketone.
**(b) Transformation:**
- **Starting Compound:** A benzaldehyde.
- **Target Compound:** A secondary alcohol with a phenyl ring.
*Proposed Reagents and Conditions:*
1. React benzaldehyde with phenylmagnesium bromide (PhMgBr) using the Grignard reaction.
2. Hydrate to form the secondary alcohol.
### Notes:
- The handwritten notes include the reagents for part (b):
1. PhBr, Mg;
2. NaBH4.
- The proposed answer for part (a) includes specific reaction conditions for reducing a carbonyl group.
Each transformation involves strategic use of organic reagents to achieve the desired molecular change.
