Question
Chapter 10.3, Problem 20PP
(a)
Interpretation Introduction
Interpretation:
Interpret the shape of CF4 according to VSEPR theory.
Concept Introduction:
The shape of a molecule can be determined with the help of VSEPR model in which Lewis structure of the molecule is drawn which shows the arrangement of surrounding atoms around the central atom.
The shape of molecule is decided by counting the lone pair of electrons along with bond pair and thus the shape of molecule is decided. Shape of molecule can be decided as:
| Bond pair | Lone pair | Geometry of molecule |
| 2 | 0 | Linear |
| 3 | 0 | Trigonal planar |
| 2 | 1 | Bent |
| 4 | 0 | Tetrahedral |
| 3 | 1 | Trigonal pyramidal |
| 2 | 2 | Bent |
| 5 | 0 | Trigonal bipyramidal |
| 4 | 1 | See saw |
| 3 | 2 | T shaped |
| 2 | 3 | Linear |
| 6 | 0 | Octahedral |
| 4 | 2 | Square planar |
