Hi
I wonder if you could help me with the following multiple choice questions:
[1] Which of the following does not have a dipole moment
a) H20 b)NH3 c)CO2 D)SF4 E)BRCL5
Are we just suppose to know that the answer is CO2 or is
there some simple way of working it out?
[2] The Lewis structure of PCl3 indicates four regions of high electron density around the phosphorus atom: one lone pair and three single bonds. What is the shape of the PCl3 molecule?
[a] Tetrahedral (b)trigonal pyramidal c)trigonal planar e) T-shape
How do we know that the answer is a trigonal pyramidal shape?
3] Similar sort of question - what is the molecular structure of IF6+
(a) octahedral (b) trigonal bypyramidal (c) square pyramidal (d) trigonal planer
In this case the number 6 denotes that it is an octahedral but often the answer is not so straightforward when non bonding pairs are concerned. How do we know if there are non bonding pairs?
