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.
1 The CH 3 - Lewis structure has a total of 8 valence electrons. 2  This includes the electron represented by the negative charge in CH 3 3  - . You need to put brackets around the CH 3 - Lewis structure as well as a negative charge to show that the structure is a negative ion. If you calculate the formal charges for CH 3 - you'll find that the Carbon (C) has a -1 charge and the Hydrogen (H) atoms each have a formal charge of zero. 2  This gives the entire structure a -1 charge (remember it's CH 3 -).
