  • question_answer
    Which of the following has maximum boiling point [IIT-JEE 1986; MP PMT 1986; CPMT 1989]

    A) iso-octane

    B) n-octane

    C) 2, 2, 3, 3-tetramethyl butane

    D) n-butane

    Correct Answer: B

    Solution :

               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.
