(a)
Interpretation:
The shape around the indicated atoms in the following compound should be determined and the lone pairs should be added to the heteroatoms:
Concept Introduction:
To add lone pair to an atom, first find the valence electron of the particular atom. After that find how many electrons are used in bond formation and then put the remaining valence electron on that particular atom.
The following table should be used while determining the shape around a carbon atom.
Number of groups | Number of atoms | Number of lone pairs | Shape | Bond angle |
2 | 2 | 0 | Linear |
|
3 | 3 | 0 | Trigonal planar |
|
4 | 4 | 0 | Tetrahedral |
|
4 | 3 | 1 | Trigonal pyramidal |
|
4 | 2 | 2 | Bent |
