<p>How would you draw the lewis dot shape of CH2BNH and would the shape look like?
Similarly, CH3PNF is also something I am having difficulty with. I am not a science person, please help, these two questions will help me set up an example of some sort for all the others!</p>
<p>THanks a bunch :)</p>
<p>Edit: Instead of the first one (CH2BNH), please try: CH2B2NH</p>
<p>Making lewis dot structures is something you just get better at after lots of practice. There are some general guidelines that can help though. Usually carbon is in the middle, so you can start there. I won't be able to draw one on this though, so I'd recommend googling it or something. As for the shape, I totally suck at that, so ask some AP chem person. Good luck.</p>
<p>Well shared electrons= needed -available. Divide that number by two to get the number of bonds you need to make. Then make it accroding to the VSEPR rules. Ask if you still need more help.</p>
<p>Remember that B is special...it can be happy with three orbitals filled in Lewis structures.</p>
<p>Ok I see that point. But the central atom is the most electronegative atom, remember that too.</p>
