Predict the molecular geometries of the following species, respectively: IF3, TeF4, XeF51+. A. trigonal pyramidal, square planar, linear B. trigonal pyramidal, tetrahedral, see-saw C. trigonal planar, tetrahedral, square pyramidal D. T-shaped, see-saw, square pyramidal E. trigonal planar, see-saw, square planar I hate shapes, not positive on the asnwer here, any help and an explanation would be great.
