Which Of The Following Compounds Has The Highest Boiling Point?
A. Propan – 1 – ol
B. n – butane
The boiling point of organic compounds depends on the molecular mass of the compounds, and the strength of the intermolecular forces.
Propan-1-ol has the highest boiling point because propan-1-ol contains H-bonding in their structure. Hence, Propan – 1 – ol has the highest boiling point amongst the given options.
Boiling points of compounds are directly related to intermolecular forces. This means if intermolecular forces are strong, the boiling point is high. Strong intermolecular forces may include H-bonding, ion-dipole attractions, and dipole-dipole interactions.
