H-Bonding

Postby Nicholas Carpo 1L » Fri Nov 16, 2018 2:25 pm

If a molecule has H-atoms does that mean there is always H-bonds as intermolecular forces? Are there any exceptions?

no h-bonding is only for polar molecules, more specifically for H-F, H-O, H-N bonds

Hydrogen bonding is the result of an especially polar bond occurring between the highly electronegative atoms of the upper right section of the periodic table (nitrogen, oxygen, and fluorine) and hydrogen. For most compounds that contain hydrogen, for instance hydrocarbons, hydrogen bonding is not presence and would therefore not be considered to be a potential intermolecular force.

Hydrogen bonding only occurs for bonds between F,O,N.

Hydrogen Bonding is between H and N,O, F and is strongest of intermolecular forces.

Hydrogen bonds only form with F O and N because they all have very strong partial negative charges due to their electronegativity, which can also be seen when you look at their location on the periodic table. This allows molecules with H and any of those atoms to bond with the strong partial positive charge of another hydrogen in an identical molecule. Hope this helps :)

F,O,N bond to Hydrogen

it's only with H and NOF

No. Typically, bonds between hydrogen and nitrogen, oxygen, and fluorine are hydrogen bonds.
