Which of the following has maximum boiling point?

Question

Which of the following has maximum boiling point? (A) n-octane (B) iso-octane (C) 2, 2, 3, 3-tetramethyl butane (D) n-butane

Tardigrade Admin · Accepted Answer

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.
