Glycerol is a ..... alcohol.

Options

A. Monohydric
B. Dihydric
C. Trihydric
D. Tetrahydric

Answer

**Step-by-Step Solution:**

1. **Understanding Alcohols**: Alcohols are organic compounds that contain one or more hydroxyl (-OH) functional groups. The classification of alcohols depends on the number of hydroxyl groups present in the molecule.

2. **Identifying Glycerol**: Glycerol, also known as glycerin, is a simple polyol compound. Its chemical structure consists of three carbon atoms, each bonded to a hydroxyl group.

3. **Counting Hydroxyl Groups**: To classify glycerol, we need to count the number of hydroxyl groups in its structure. Glycerol has three -OH groups attached to it.

4. **Classifying Glycerol**: Based on the number of hydroxyl groups:
- Mono-hydric alcohols have one -OH group.
- Di-hydric alcohols have two -OH groups.
- Tri-hydric alcohols have three -OH groups.
- Tetrahydric alcohols have four -OH groups.

Since glycerol has three -OH groups, it is classified as a tri-hydric alcohol.

5. **Conclusion**: Therefore, the answer to the question is that glycerol is a tri-hydric alcohol.
