Concept explainers
(a)
Interpretation:The given skeletal structure of amoxicillin needs to be completed.
Concept Introduction: Single bond has all sigma bonds; double bond has 1 sigma and 1 pi bond and triple bond has 2 sigma and 1 pi bond. The lone pair of electrons are those electrons which do not take part in bonding. Generally, carbon has zero lone pair, oxygen has 2 lone pairs, sulfur has 2 lone pairs and nitrogen has 1 lone pair of electrons.
(b)
Interpretation:The hybridization and 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.
(c)
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.
(d)
Interpretation:The most polar bond in amoxicillin needs to be detremined.
Concept Introduction: A bond is said to be polar if there is electronegativity difference between the atoms.
(e)
Interpretation:The amoxicilllin needs 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.
(f)
Interpretation:Whether amoxicillin expected to 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.

- Answer true or false. (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. (e) Ionic bonds tend to form between elements on the left side of the Periodic Table, and covalent bonds tend to form between elements on the right side of the Periodic Table. (f) Ionic bonds tend to form between a metal and a nonmetal. (g) When two nonmetals combine, the bond between them is usually covalent.
