Concept explainers
(a)
Interpretation:
The number of lone pairs on the dark red atom needs to be determined. An example of molecule having this geometry needs to be determined.
Concept Introduction:
Lewis structures can be used to determine the shape around an atom in a molecule. In order to determine the shape of a central atom, first the number of atoms surrounded by it needs to be determined.
The valence shell electron pair repulsion (VSEPR) theory can be used to determine the shape around an atom.
(b)
Interpretation:
Thenumber of lone pair of electrons needs to be determined in the molecule. An example should be given for the type of the molecule.
Concept Introduction:
Molecules follow octet rule and depending on the number of lone pairs in the central atom, they form different molecular shapes.
