a) CHCl3, chloroform
Interpretation:
The line – bond structure, showing all nonbonding electrons for CHCl3, chloroform is to be given.
Concept introduction:
A covalent bond is formed by mutual sharing of two electrons between the atoms, each atom giving one electron for sharing. Such a covalent bond, that is, a pair of shared electrons is represented as a line between the atoms, for example as A-B. Valence electrons that are not used for bonding are called lone-pair of electrons or nonbonding electrons. The nonbonding electrons are usually omitted while drawing line-bond structure.
