Is a bond between hydrogen and nitrogen a hydrogen bond?

Answer 1

It depends.

In an individual molecule, covalent bonds hold the nitrogen atom to the hydrogen atom. This is a type of a intramolecular force and is responsible for holding the atoms in a molecule together.

In a group of NH containing molecules, the force responsible for holding the molecules together is due to is the hydrogen bond. This is a intermolecular force and is responsible for holding the molecules together.

So basically, if the hydrogen and nitrogen are in the same molecule it's not a hydrogen bond and if they're not in the same molecule and there's a still an attraction it is a hydrogen bond.

Answer 2

Both nitrogen gas (N2) and hydrogen gas (H2) are diatomic molecules. They both have non-polar covalent bonds. However, H2 has a single bond, whereas N2 has a triple bond (and so N2 has a much stronger bond)

Answer 3

Ordinarily hydrogen gas and nitrogen gas do not form bonds. It takes a special process called nitrogen fixation to bond three hydrogen atoms to one nitrogen atom, forming ammonia.

There are several ways nitrogen fixation can happen:

1. in a lightning bolt a brief high temperature reaction occurs, this is inorganic nitrogen fixation and is both inefficient and rare.
2. In a few species of anaerobic bacteria they have enzymes that perform nitrogen fixation, this is organic nitrogen fixation and is very efficient but these bacteria are killed by the oxygen in the air. they can usually only function in a symbiotic relationship with certain plants that let the nitrogen fixing bacteria form nodules on their roots.
3. In an artificial chemical process called the Haber-Bosch process that requires very high temperature, very high pressure, and special catalysts, this is inorganic nitrogen fixation and is very efficient. Most fertilizers and explosives are manufactured using ammonia made by this process.
