The ph3 molecule is polar. does this offer experimental proof that the molecule cannot be planar? explain.

Answer: if it was planar the center of the negative forces and the center of the positive forces would be at the same place, meaning no di-poles would form so it wouldnt be polar. as it is polar it therefore cannot be planar. the neagative center (pole) is above the the positive one due to the pair of unbonded electrons.
