Acetic acid is treateed with `Ca(OH)_(2)` and the product so obtained is subjected to dry distillation. The final products is

Options

A. propanal
B. ethanol
C. ethanal
D. propanal

Explanation

To solve the problem, let's break it down step by step:

### Step 1: Reaction of Acetic Acid with Calcium Hydroxide
Acetic acid (CH₃COOH) reacts with calcium hydroxide (Ca(OH)₂) in a neutralization reaction to form calcium acetate (CH₃COO)₂Ca. This is a typical acid-base reaction where the acid reacts with the base to form a salt and water.

**Chemical Equation:**
\[ \text{CH}_3\text{COOH} + \text{Ca(OH)}_2 \rightarrow \text{(CH}_3\text{COO)}_2\text{Ca} + \text{H}_2\text{O} \]

### Step 2: Dry Distillation of Calcium Acetate
The calcium acetate formed is then subjected to dry distillation. During dry distillation, calcium acetate decomposes to produce acetone (CH₃COCH₃), calcium oxide (CaO), and carbon dioxide (CO₂).

**Chemical Equation:**
\[ \text{(CH}_3\text{COO)}_2\text{Ca} \xrightarrow{\text{Dry Distillation}} \text{CaO} + \text{CO}_2 + \text{CH}_3\text{COCH}_3 \]

### Step 3: Identify the Final Products
From the dry distillation of calcium acetate, the products formed are:
- Calcium oxide (CaO)
- Carbon dioxide (CO₂)
- Acetone (CH₃COCH₃)

Thus, the final products of the reaction are acetone, calcium oxide, and carbon dioxide.

### Final Answer:
The final products obtained from the dry distillation of acetic acid treated with calcium hydroxide are **acetone (CH₃COCH₃), calcium oxide (CaO), and carbon dioxide (CO₂)**.
