Question

Hydrogen bonding is responsible for: Select the correct answer below:a. the unexpectedly high boiling points for binary molecular hydrides (XHn) in period two b. the increasing boiling points for binary molecular hydrides (XHn) going down a group c. the low boiling points of nonpolar molecules d. none of the above

Answer 1

Answer:

A

Explanation:

First there is molecular size. Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules. ... Molecular shape is also important, as the second group of compounds illustrate.
