Which of the following compounds does not react with NaOH ?

Options

A. `CH_(3)COOH`
B. `CH_(3)CONH_(2)`
C. `C_(6)H_(5)OH`
D. `CH_(3)CH_(2)OH`

Explanation

To determine which compound does not react with NaOH, we will analyze each of the given options step by step.

### Step 1: Analyze CH3COOH (Acetic Acid)
- **Reaction**: CH3COOH + NaOH → CH3COO⁻Na⁺ + H2O
- **Type of Reaction**: This is an acid-base neutralization reaction where acetic acid (a weak acid) reacts with sodium hydroxide (a strong base) to form sodium acetate and water.
- **Conclusion**: CH3COOH reacts with NaOH.

### Step 2: Analyze CH3CONH2 (Acetamide)
- **Reaction**: CH3CONH2 + NaOH → CH3COO⁻Na⁺ + NH3
- **Type of Reaction**: This reaction involves the hydrolysis of an amide in an alkaline medium, producing a carboxylic acid (sodium acetate) and ammonia.
- **Conclusion**: CH3CONH2 reacts with NaOH.

### Step 3: Analyze C6H5OH (Phenol)
- **Reaction**: C6H5OH + NaOH → C6H5O⁻Na⁺ + H2O
- **Type of Reaction**: This is also an acid-base neutralization reaction where phenol (a weak acid) reacts with sodium hydroxide to form sodium phenoxide and water.
- **Conclusion**: C6H5OH reacts with NaOH.

### Step 4: Analyze Ca3Ca2OH (Calcium Hydroxide)
- **Reaction**: Ca3Ca2OH + NaOH → No reaction
- **Type of Reaction**: Calcium hydroxide is a strong base and does not undergo a reaction with another strong base like NaOH. Additionally, alcohols are very weak acids and do not react with NaOH.
- **Conclusion**: Ca3Ca2OH does not react with NaOH.

### Final Answer
- The compound that does not react with NaOH is **Ca3Ca2OH**.
