Orbital overlap diagram for ammonia

    1. The problem statement, all variables and given/known data

    2. Relevant equations
    none
    This is how I was taught to draw orbital overlap diagrams in my lesson:

    3. The attempt at a solution

    I have drawn four attempts for a possible orbital overlap diagram of NH3:

    Attempt # 1:

    For this one, are the atoms arranged correctly? should it be two hydrogen at the bottom and one at the top?

    Attempt # 2:

    For this one, it doesn't really follow the example taught in the lesson, but does it make sense to do it like this?

    Attempt # 3:

    should I be hybridizing it...?


    Attempt # 4:

    Can someone please tell me which and if any of these diagrams are correct?

    Any help is appreciated. Thanks :)

    These "Orbital Overlap Diagrams" are very cartoonish representations, so it is hard to say which is wrong or right. I like attempt #2, as it is neater. In the example of water, no hybridization is used for the oxygen, therefore I would guess that it is not necessary to use hybridization for N.
