Clindamycin is indicated in the treatment of serious infections caused by susceptible anaerobic bacteria.
Confidence votes 297. PH3 has 3 bonding pairs and 1 non-bonding pair of electrons. Its electron pair geometry is Tetrahedral and its molecular geometry is Trigonal Pyramidal.ou might think trigonal planar, but it's actually trigonal pyramidal. Remember that phosphorus (like nitrogen) ends up with a lone pair when it bonds to three things covalent â¦ ly. That lone pair causes a lot of distortion and you end up with the pyramid shape.
In chemistry, a trigonal pyramid is a molecular geometry with one atom at the apex and three atoms at the corners of a trigonal base.When all three atoms at the corners are identical, the molecule belongs to point group C3v.his would result in the geometry of a regular tetrahedron with each bond angle cosâ1(ââ) â 109.5Â°. However, the three hydrogen atoms are repelled by the electron lone pair in a way that the geometry is distorted to a trigonal pyramid (regular 3-sided pyramid) with bond angles of 107Â°.
