Options

A. Phenol
B. Glycol
C. Glycerol
D. Formaldehyde

Explanation

To solve the question regarding alkyd resins and their components, we can follow these steps:

### Step 1: Understand Alkyd Resins
Alkyd resins are a type of synthetic polymer that are formed through a condensation reaction. They are primarily used in paints and coatings due to their durability and glossy finish.

**Hint:** Alkyd resins are formed through a reaction involving acids and alcohols.

### Step 2: Identify the Components of Alkyd Resins
Alkyd resins are produced from two main types of compounds:
- **Dibasic acids**: These are acids that contain two carboxylic acid groups (-COOH).
- **Polyhydric alcohols**: These are alcohols that contain two or more hydroxyl groups (-OH).

**Hint:** Look for compounds that have multiple functional groups, specifically two carboxylic acid groups for dibasic acids and two or more hydroxyl groups for polyhydric alcohols.

### Step 3: Example of Polyhydric Alcohol
One common example of a polyhydric alcohol used in the formation of alkyd resins is glycerol. Glycerol has three hydroxyl groups and is represented as CH2OH-CHOH-CH2OH.

**Hint:** Remember that polyhydric alcohols have multiple -OH groups, which are essential for the formation of the polymer.

### Step 4: Conclusion
Based on the information provided, the alkyd resins are condensation polymers obtained from dibasic acids and polyhydric alcohols, with glycerol being a specific example of a polyhydric alcohol used in this process.

**Final Answer:** The alkyl resins are condensation polymers obtained from dibasic acids and glycerol.
