And if not writing you will find me reading a book in some cozy cafe ! The bond angles are all 90°, and just as four electron pairs experience minimum repulsion when they are directed toward the corners of a tetrahedron, six electron pairs try to point toward the corners of an octahedron. The outer atoms and the lone pair of electrons are not attracted to each other. Answer Save. Then you've got it 99% done. There are two dimensions of Phosphorus Trichloride.
