Concept explainers
(a)
Interpretation: The geometry of each central atom in the given structure needs to be determined.
Concept Introduction: Hybridization is defined as mixing of orbital. The geometry of a central atom depends on its hybridization. The shape will be different from geometry if there are lone pair of electrons present on the central atom.
(b)
Interpretation:The bond angles associated with each central atom needs to be determined.
Concept Introduction: The bond angles of central atom can be determined from its hybridization and geometry.
(c)
Interpretation:The most polar bond in given structure needs to be determined.
Concept Introduction: A bond is said to be polar if there is electronegativity difference between the atoms.
(d)
Interpretation:The given moleculeneeds to be classified as a polar or non-polar molecule.
Concept Introduction: If there are polar bonds present in a molecule then it is considered as a polar molecule.
(e)
Interpretation:Whether given molecule possess resonance or not needs to be explained.
Concept Introduction: Resonance is possessed by a molecule if there is possibility of delocalization of electrons. This can be positive if there is intercation between alternate lone pairs and pi bonds present in a molecule.

(a) According to the Lewis model of bonding, atoms bond together in such a way that each atom par- ticipating in the bond acquires an outer-shell electron configuration matching that of the noble gas nearest to it in atomic number. (b) Atoms that lose electrons to achieve a filled valence shell become cations and form ionic bonds with anions. (c) Atoms that gain electrons to achieve filled valence shells become anions and form ionic bonds with cations. (d) Atoms that share electrons to achieve filled valence shells form covalent bonds.
