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.

Interpretation Introduction
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 Introduction
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 Introduction
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 Introduction
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 Introduction
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.
