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.
Electron geometry should be trigonal planar because there are three regions of electron density about nitrogen (one single bond,one double bond, one lone pair). The molecular geometry should be bent and it should be somewhat less than 120 deg because the lone pair takes up more volume than a bond.eport Abuse. Start by drawing O-N-O. Count the total number of valence electrons. 6 for each oxygen (12) plus 5 for nitrogen plus one for the negative charge, total of 18. Count the bonds you used (4 electrons) and you've got 14 left. Put lone pairs around the terminal atoms (oxygens) to satisfy their octets.
