Question

Which of the following has maximum boiling point

• A. Iso-octane
• B. n-octane
• C. 2, 2, 3, 3-tetramethyl butane
• D. n-butane

Answer 1

The correct option is B n-octane

n–octane
1) Boiling point depends on molecular mass. Greater the molecular mass higher will be the boiling point.

2) Boiling point also depends on the structure. If two compounds have same molecular mass then straight chain or linear compound has higher boiling point.
