bellow are ball and stick models of two molecules, in each case, indicate where there must be, may be, or cannot be one or more lone pairs of electrons on the central atom
The picture is of a trigonal planar molecule with 120 degrees between it and then a linear molecule with 180 degrees
But if there were lone pairs would the angle on the first one be less the 120 degrees and the second one as well?
Thanks so much!
