On the basic intermolecular force predict the correct order of decreasing bolling point of the compound ?

Options

A. `CH_(3)OHgtH_(2)gtCH_(4)`
B. `CH_(3)OHgtCH_(4)gtH_(2)`
C. `CH_(4)gtCH_(3)OHgtH_(2)`
D. `H_(2)gtCH_(4)gtCH_(3)OH`

Explanation

To determine the correct order of decreasing boiling points of the compounds methyl alcohol (methanol), hydrogen (H2), and methane (CH4), we will analyze the intermolecular forces present in each compound.

### Step-by-Step Solution:

1. **Identify the Compounds and Their Intermolecular Forces**:
- **Methyl Alcohol (Methanol, CH3OH)**: This compound exhibits hydrogen bonding due to the presence of an -OH (hydroxyl) group. Hydrogen bonding is a strong intermolecular force.
- **Hydrogen (H2)**: This is a diatomic molecule with nonpolar covalent bonds. The only intermolecular forces present are weak Van der Waals (London dispersion) forces.
- **Methane (CH4)**: This is also a nonpolar molecule with weak Van der Waals forces similar to hydrogen.
