Solution: The boiling points, surface tensions, and viscosities of water and several alcohols are as follows: Boiling Point (oC) Surface Tension (J/m2) Viscosit

Problem
The boiling points, surface tensions, and viscosities of water and several alcohols are as follows:

Boiling Point (oC) Surface Tension (J/m2) Viscosity (kg/m s)
Water, H2O 100 7.3 10 - 2 0.9 10 - 3
Ethanol, CH3CH2OH 78 2.3 10 - 2 1.1 10 - 3
Propanol, CH3CH2CH2OH 97 2.4 10 - 2 2.2 10 - 3
n-Butanol, CH3CH2CH2CH2OH 117 2.6 10 - 2 2.6 10 - 3
Ethylene glycol, HOCH2CH2OH 197 4.8 10 - 2 26 10 - 3

For ethanol, propanol, and n-butanol the boiling points, surface tensions, and viscosities all increase. What is the reason for this increase?
