H-bonding Question

Postby Bita Ghanei 1F » Tue Nov 19, 2019 8:57 am

3F.1 Identify the types of attractive intermolecular interactions that might arise between molecules of each of the following substances: (a) NH2OH;(b) CBr4;(c) H2SeO4;(d) SO2.

For C, H2SeO4, is the only reason that Hbonds are a valid answer because there is an O-H bond in the lewis structure AND an Oxygen that is available for bonding in the same lewis structure?

What makes a molecule qualify as having H-bond IMFs? Thanks!

Yes, because of the alcohol group, there is H-bonding. For a molecule to have H-bonding, hydrogen must be bonded to O, N, or F, and those atoms must also have a lone pair.

Certain questions may ask for all hydrogen bonding sites, which would be all the lone pairs and hydrogen bondings to N O and F in a molecule.
