Question

Which of the following has the highest bolling point?

• A. $C{H}_4$
• B. $C{F}_4$
• C. $CC{l}_4$
• D. $C_2{H}_2$

Answer 1

The correct option is C $CC{l}_4$

Boiling points of non-polar molecules is decided by van der Waal forces of attraction.
The boiling point of a molecule is directly proportional to its molecular weight.
Here, all the molecules are non-polar, out of which $CC{l}_4$ has the greatest molecular weight and so, it will have the highest boiling point.
