UA worksheet question

Postby Arya_Naeim_1H » Thu Dec 07, 2023 11:45 am

A UA worksheet stated that C10H22 has a higher boiling point than water because it was larger. However I thought H2O has a high boiling point due to hydorgen bonds. Can someone explain the answer?

Sometimes, we have to look at molecular mass/weight in order to determine which has a higher boiling point. In the case of C10H22, it has a massive molar mass (about 142 g/mol), many times greater than water (about 18 g/mol). This large discrepancy in molar mass makes C10H22 to have a higher boiling point.
