MCQ
Which of the following has maximum boiling point
- Aiso-octane
- ✓$n-$ octane
- C$2, 2, 3, 3-$ tetramethyl butane
- D$n-$ butane
✓
Answer
Correct option: B.
$n-$ octane
b
(b)$ n-$ octane
(b)$ n-$ octane
* Boiling point depends on molecular mass. Greater the molecular mass higher will be the boiling point.
*Boiling point also depends on the structure. If two compounds have same molecular mass then straight chain or linear compound has higher boiling point.
