Concept explainers
(a)
Interpretation:
Interpret number of valence electron, bond pair and lone pair in the given Lewis structure.
Concept Introduction:
Valence electrons are the electrons present in the outermost orbital or shell of an atom which participates in the formation of bond with another atom.
The bond formed between two atoms by sharing of electrons is known as covalent bond. A single
Total number of valence electron can be determined by adding all the electrons present in the outermost shell of each atom present in a molecule.
For example, in HxOy
Total number of valence electron = number of H (valence electron of H) + number of O (valence electron of O)
(b)
Interpretation:
Interpret number of valence electron, bond pair and lone pair in the given Lewis structure.
Concept Introduction:
Valence electrons are the electrons present in the outermost orbital or shell of an atom which participates in the formation of bond with another atom.
The bond formed between two atoms by sharing of electrons is known as covalent bond. A single chemical bond is formed by sharing of 2 electrons while double bond is formed by sharing of 4 and triple bond is formed by sharing of 6 electrons.
Total number of valence electron can be determined by adding all the electrons present in the outermost shell of each atom present in a molecule.
For example, in HxOy
Total number of valence electron = number of H (valence electron of H) + number of O (valence electron of O)

- A mixture of C7H12O2, C9H9OCl, biphenyl and acetone was put together in a gas chromatography tube. Please decide from the GC resutls which correspond to the peak for C7,C9 and biphenyl and explain the reasoning based on GC results.
