Hydrocarbons Question 176
Question: Which of the following has maximum boiling point [IIT-JEE 1986; MP PMT 1986; CPMT 1989]
Options:
A) iso-octane
B) n-octane
C) 2, 2, 3, 3-tetramethyl butane
D) n-butane
Show Answer
Answer:
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.
