Concept explainers
(a)
Interpretation:
Interpret and match the lewis structure (a) with the correct diagram from 1, 2 or 3. Write down the name of shape and indicate whether it is polar or non-polar.
Concept Introduction:
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 |
(b)
Interpretation:
Interpret and match the lewis structure (b) with the correct diagram from 1,2 or 3. Write down the name of shape and indicate whether it is polar or non-polar.
