How can I visualize the net dipole moment in 3D structures? For example, in CH
4 , it is deemed non polar. However, I don't quite 'see' it. The pyramidal base has a dipole moment acting upwards and the top of it where there is a C-H bond, it acts downwards. So it cancels out and has no net dipole moment.
I am unable to understand how they cancel out. So for a lot of 3D structures like CH
3 CH
2 CH
3 or CH
3 CF
2 CH
3 I can't really tell by myself about their net dipole moments. I would have to google it.
Can someone enlighten me? Thanks
