Answer :
Answer:
the molecules that can form hydrogen bonds with water molecules are:
- **CH₃OH (Methanol)**
- **CH₃NH₂ (Methylamine)**
So, the correct response includes both **CH₃OH** and **CH₃NH₂**.
Explanation:
Hydrogen bonding occurs when a hydrogen atom is directly bonded to a highly electronegative atom, such as oxygen (O), nitrogen (N), or fluorine (F). Water molecules (H₂O) can form hydrogen bonds with other molecules that have hydrogen atoms bonded to these electronegative atoms.
Let's analyze the given molecules:
1. **CH₃OH (Methanol)**:
- Methanol has an -OH group, where hydrogen is bonded to oxygen.
- This makes CH₃OH capable of forming hydrogen bonds with water molecules through the -OH group.
2. **CH₄ (Methane)**:
- Methane has hydrogen atoms bonded to carbon.
- Carbon is not sufficiently electronegative to facilitate hydrogen bonding.
- Therefore, CH₄ cannot form hydrogen bonds with water molecules.
3. **CH₃NH₂ (Methylamine)**:
- Methylamine has an -NH₂ group, where hydrogen is bonded to nitrogen.
- This makes CH₃NH₂ capable of forming hydrogen bonds with water molecules through the -NH₂ group.
Thus, the molecules that can form hydrogen bonds with water molecules are:
- **CH₃OH (Methanol)**
- **CH₃NH₂ (Methylamine)**
So, the correct response includes both **CH₃OH** and **CH₃NH₂**.
