MCQ
What is the dominant intermolecular force or bond that must be overcome in converting liquid $CH_3OH$ to a gas?
- ADipole-dipole interaction
- BCovalent bonds
- CLondon dispersion force
- ✓Hydrogen bonding
✓
Answer
Correct option: D.
Hydrogen bonding
d
When $H$ atom is directly linked with $N, O,$ or $\mathrm{F}$, inter or intramolecular $H-$ bonding is formed.
When $H$ atom is directly linked with $N, O,$ or $\mathrm{F}$, inter or intramolecular $H-$ bonding is formed.
In between $\mathrm{CH}_{3} \mathrm{OH}$ molecules, intermolecular $H-$bonding exists.
Hence, it is the intermolecular $\mathrm{H}$ - bonding that must be overcome in converting liquid $\mathrm{CH}_{3} \mathrm{OH}$ to gas.
