MCQ
In paraffins, with the increasing molecular weight, it is found that
- AFreezing point decreases
- BBoiling point decreases
- ✓Boiling point increases
- DVapour pressure decreases
✓
Answer
Correct option: C.
Boiling point increases
c
(c) Paraffins are non-polar compounds. The intermolecular forces are weak Vander Waal’s forces. As the molecular mass increases Vander Waal’s forces increases. Hence boiling point increases.
