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.

If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used.
