H-Bond acceptor

[Cecilia Cisneros 1F]

Does an H-bond acceptor (O,N, or F) need to be attached to a hydrogen atom to participate in h-bonds?

[Hannah Biju 1E]

The hydrogen needs to be connected to an N,O, or F to have a partial positive but the other molecule's only restriction is that it must have a partial negative. For example, a hydrogen bonded to N,O, or F can form a hydrogen bond with an oxygen bonded to a carbon because the oxygen is more electronegative than the carbon giving it a partial negative charge

[Jared Limqueco 3E]

Just like above, a partial charge is needed, and a there has to be an available lone pair as well

[AndrewNguyen_2H]

No, you need one hydrogen bonded to F, O, or N but the other F, O,N that bonds to that hydrogen doesn't need to be connected to hydrogen.

[Jason_John_2F]

the hydrogen bond acceptor does not need to be attached to a hydrogen

[DavidTabib 3H]

Only one of the H needs to be attached to a NOF element.

[David Liu 1E]

it doesn't need to be attached to a hydrogen, but you need ot make sure there's a partial charge on the molecule that it's attached to, which is why in the sapling homework it generally can't attach to a carbon that has 4 bonds (because it becomes nonpolar)

[Alejandro Gonzalez 2G]

I think the hydrogen bond acceptor does not need to be attached to another hydrogen itself, but just needs to have a partial negative charge.

[Sophia Kalanski 1A]

No, the hydrogen needs to be attached to either F,N,O but the other atom just has to be electronegative.

[Callan Howard]

No there just has to be a hydrogen attached to an F, O or N.
