A vic diol has two hydroxy1 group on…………………….`C` atoms

Explanation

**Step-by-Step Solution:**

1. **Understanding Vic Diol**: A vic diol, also known as a vicinal diol, is a type of organic compound that contains two hydroxyl (-OH) groups. The term "vicinal" refers to the position of these hydroxyl groups on the carbon chain.

2. **Position of Hydroxyl Groups**: In a vic diol, the two hydroxyl groups are located on adjacent carbon atoms. This means that if we have a chain of carbon atoms, the two carbons that bear the hydroxyl groups are next to each other.

3. **Example Structure**: For instance, if we consider a simple chain of two carbon atoms (C1 and C2), a vic diol would have the structure where both C1 and C2 have hydroxyl groups attached. This can be represented as:
- C1 - OH
