H20 to H2S
Is h20 to h2s considered a hydrogen bond because the S has a lone pair that can be attached to the h20 which is h-O bond?

Re: H20 to H2S
I think only molecules with N-H, O-H, and F-H bonds can form strong hydrogen bonds. This article mentioned that hydrogen bonds between H2O and H2S are "transient," lasting no more than 10 ps, and are weak. https://www.researchgate.net/publicatio ... avior#pf16

Re: H20 to H2S
H2S has no hydrogen bonds while H2O does. Because of this, we're able to explain why water has both a higher boiling and melting point than hydrogen sulphide. (Water's boiling point is 100 degrees Celsius vs hydrogen sulphide's boiling point of only -60 degrees Celsius. Water also has a higher melting point at 0 degrees Celsius vs hydrogen sulphide's melting point at only -86 degrees Celsius.)

Re: H20 to H2S
I think that there can only be hydrogen bonds when there is an H attached to an N,O, or F that attaches to another N, O, or F that has an available lone pair. I don't think that H2O to H2S would have a hydrogen bond since the lone pair is on an S atom, not an N, O, or F atom.
Re: H20 to H2S
Hydrogen bonding can happen only when the hydrogen is in a polar molecule and the other atom in the hydrogen bonding is electronegative (N, F, O).
I think in this case, water would prefer to form hydrogen bond within itself rather than hydrogen bonding with H2S.
