An Unbiased Viewpoint on pros and cons crude oil. I penned this Commentary because I felt compelled to clarify some of the uninformed statements made about pros and cons crude oil. Hopefully you'll discover some useful facts to capitalize on. At the very least the press corps can slash away at my opinions..Crude Oil is a smelly, yellow-to-black liquid and is usually found in underground areas called reservoirs. The story of pros and cons crude oil is even a bit more noteworthy.opefully you'll discover some useful facts to capitalize on. At the very least the press corps can slash away at my opinions..

The electron pair arrangement that minimizes repulsion for 3 pairs of electrons is trigonal planar. The angles between electron pairs are 120. The molecular geometry is the arrangement of the central atom and the atoms bonded directly to it. In BF3, all 3 electron pairs around boron are bonding pairs.
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.
