Hydrogen Bonding

[Alara Aygen 3K]

Hi! Can someone explain me why two NO molecules cannot form hydrogen bonds?

[Chem_Mod]

They cannot form a hydrogen bond because there is no hydrogen.

[Crystal Hsueh 2L]

In order to have a hydrogen bond, one of the molecules must have a hydrogen attached to either N,O, or F and the molecule it is bonding to must have a lone pair of electrons on a highly electronegative atom (N, O, or f). Two NO molecules cannot hydrogen bond because there is no hydrogen atom involved.

[Kailani_Dial_2K]

A hydrogen bond requires a Hydrogen attached to a NOF which will then bond with another NOF that has a lone pair. NO does not have a hydrogen so there can be no hydrogen bond between two NOs . However, an NO molecule could H-bond with say a H2O molecule.

Hi! I have these notes written down that summarize hydrogen bonding that is repetitive but might help you:
-N,O, or F shares a lone pair of e- with positively polarized (electron-deficient) H
-partially positive H is bonded to a partially negative N, O, or F
-There must be one of these three bonds: O-H, N-H, F-H
-N, O, F are all so electronegative that they withdraw the majority of the electron density in the covalent bond with hydrogen, leaving the H atom very electron-deficient.

[Muskaan Abdul-Sattar]

In order to form a hydrogen bond, there must be hydrogen present!

[Wenhan Li_3d]

Hydrogen bonds need a hydrogen in either of one, however NO has no Hydrogen, therefore can not form hydrogen bond.

[Harshitha_Pandian_3F]

To form a H-bond, there needs to be a hydrogen bonded to either a N, O or F atom and that atom should be partially negative charged. This is not true for the two NO molecules as there is no H that is bonded to either the N or the O molecule.
