Let's solve question **12.a** step by step:
## Step 1: Reaction of Compound A to Compound B
**Reagents:** 1. Excess LiAlH₄, 2. H₂O
- **Reaction Type:** Reduction of a carboxylic acid by lithium aluminum hydride (LiAlH₄).
- **Explanation:** LiAlH₄ is a strong reducing agent that reduces carboxylic acids to primary alcohols.
### Structure:
- Compound A:
 (benzoic acid)
- Compound B:
The carboxylic acid (-COOH) group is reduced to a primary alcohol (-CH₂OH).
**Product B:**
Benzyl alcohol (C₆H₅CH₂OH)
---
## Step 2: Reaction of Compound B to Compound C
**Reagents:** PCC (Pyridinium chlorochromate), CH₂Cl₂
- **Reaction Type:** Oxidation of primary alcohol to aldehyde.
- **Explanation:** PCC selectively oxidizes primary alcohols to aldehydes without further oxidation to carboxylic acids.
### Structure:
- Compound B: Benzyl alcohol (C₆H₅CH₂OH)
- Compound C: Benzaldehyde (C₆H₅CHO)
**Product C:**
Benzaldehyde
---
## Final Answer
### 12.a:
- **Compound B:** Benzyl alcohol (C₆H₅CH₂OH)
- **Compound C:** Benzaldehyde (C₆H₅CHO)
### 12.b:
- **Is B being oxidized or reduced?**
**B is being oxidized** (primary alcohol to aldehyde).
