Why can't SO2 form Hydrogen bonds?

Postby Mario Reyes 1C » Fri Jun 08, 2018 6:33 pm

On the homework problem 6.1 d) hydrogen bonding was not an answer. Why wouldn't SO2 be able to form hydrogen bonds, even though it has an oxygen with an available lone pair?

I think this question is asking what intermolecular forces would arise between two SO2 molecules, given that there is no hydrogen in SO2, there would be no hydrogen bonding between two molecules of sulfur dioxide, which is why hydrogen bonding is not an answer.

However, because SO2 does have oxygen atoms with lone pair electrons, it would be able to form a hydrogen bond with a molecule that has an O--H, N--H, or F--H bond.

is it because there isn't a partially negative charge?

SO2 can't form hydrogen bonds because there is no hydrogen. The bonds are polar as the S is slightly positive and the O is slightly negative, so there is some intermolecular bonding happening there, but without hydrogen, they are not classified as hydrogen bonds.
