Weak Bases with Nitrogen

Dr. Lavelle said something about nitrogen in the compound needing a lone pair or else it can’t act as a base. Can someone remind me why that lone pair is necessary?

I'm not sure how right I am, but I'll give this a shot. I think that nitrogen has the lone pair because the free electron pair in nitrogen shares those electrons with a proton to form a cation. So when NH3 is reacted with H20, it shares that electron pair with the hydrogen atom in H2O.

Dr. Lavelle said that if. a molecule has Nitrogen in it and that Nitrogen has a lone pair then it acts as a base. It is like in a DNA molecule where the nitrogen in the base pair gives up its lone pair.

According to the Lewis definition of a base, a base is a lone pair donor.

It is important to know that a base is an e- donor!!
