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.
B forms 3 bonds (has 3 valence electrons) and is sp2 hybridized, so the molecule is trigonal planar, which is symmetrical. P can form 5 bonds (has 5 valence electrons), and in â¦ PCl3 has a free electron pair which makes the molecule non-symmetrical.
