Question

Which Alkane shows highest boiling point? *
1 point
a) 2- Methyl Propane
b) Pentane
c) 2- Methyl butane
d) 2,2- Dimethyl propane​

Answer 1

Explanation:

1. Nonane will have a higher boiling point than octane, because it has a longer carbon chain than octane. 2. Octane will have a higher boiling point than 2,2,3,3‑tetramethylbutane, because it branches less than 2,2,3,3‑tetramethylbutane, and therefore has a larger “surface area” and more van der Waals forces.
