In chemistry, T-shaped molecular geometry describes the structures of some molecules where a central atom has three ligands.Ordinarily, three-coordinated compounds adopt trigonal planar or pyramidal geometries. PCl3 is a dipole since it is asymmetrical. The angle between each of the bonds in the molecule is 90 degrees for the four fluorine atoms making up the base of the pyramid, and 180 degrees for the single fluorine atom making up the pyramid's point. If you want to quickly find the word you want to search, use Ctrl + F, then type the word you want to search. The idea of a correlation between molecular geometry and number of valence electron pairs (both shared and unshared pairs) was originally proposed in 1939 by Ryutaro Tsuchida in Japan, and was independently presented in a Bakerian Lecture in 1940 by Nevil Sidgwick and Herbert Powell of the University of Oxford.
