Which of the following is zerone?

Options

A. `MeOH`
B.
C.
D. `EtOH`

Explanation

To determine which of the given options is known as "zerone," we will analyze each option step by step.

### Step 1: Identify the Compounds
The options provided are:
1. Methanol (CH3OH)
2. Ethylene Glycol (CH2OH-CH2OH)
3. Glycerol (C3H8O3)
4. Ethanol (C2H5OH)

### Step 2: Understand the Definition of Zerone
Zerone is a term that is typically used to refer to methanol. It is important to note that the term "zerone" is not widely used in modern chemistry, but in this context, it is associated with methanol.

### Step 3: Analyze Each Compound
- **Methanol (CH3OH)**: This is a simple alcohol and is indeed referred to as zerone in some contexts.
- **Ethylene Glycol (CH2OH-CH2OH)**: This is a diol (a compound with two hydroxyl groups) and is not referred to as zerone.
- **Glycerol (C3H8O3)**: This is a trihydric alcohol (having three hydroxyl groups) and is not referred to as zerone.
- **Ethanol (C2H5OH)**: This is a common alcohol but is not referred to as zerone.

### Step 4: Conclusion
Among the four options, **methanol (CH3OH)** is the only compound that is referred to as zerone.

### Final Answer
**Methanol (CH3OH) is zerone.**
