Re: Weak Bases with Nitrogen
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.

An example could be the heating of ethylene (C2H4). The heat causes the pi bonds to break by rotating it back and forth, thus breaking that bond.

A wave function is used to describe it because an electron has wave like properties. So because we cannot know both the momentum AND the position, we utilize a wave function.
