The boiling point of:
(a) 1-propanol is 97 °C
(b) 1,2-propanediol is 214 °C and
(c) 1,2,3-propanetriol is 270 °C
What factors contribute to the increasing boiling points within the series?
1 answer
The increasing boiling points within the series can be attributed to the increase in molecular weight and the number of hydrogen bonding sites. As the number of carbon atoms and/or the number of hydroxyl groups increase, so does the molecular weight and the ability to form more hydrogen bonds. This results in stronger intermolecular forces and a higher boiling point.
