Clindamycin is indicated in the treatment of serious infections caused by susceptible anaerobic bacteria.

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.
Report Abuse. PH3 molecule has the central atom of phosphorus connected by single bonds to three hydrogen atoms. The phosphorus atom also has one pair of unshared electrons.The electron-cloud geometry of the phosphorus atom is tetrahedral, but the molecular geometry of phosphorus trihydride is trigonal pyramidal, when the nuclei of the three hydrogen atoms are each connected to the nucleus of the phosphorus atom.est Answer: Bent-only works with two substituents. Linear works with one. Tetrahedral only works with four, so you're left with trigonal planar and trigonal pyramidal. Look what you know about P: it has 5 electrons, but in PH3 it is only using three, so the odd pair have to go somewhere.
