What do you understand by bond pairs and lone pairs of electrons? Illustrate by giving one example of each type.
(N/A) Bonding electron pair: In a molecule,the electron pair which forms a bond between two atoms is called a bonding electron pair.
Nonbonding electron pair (lone pair): The electron pair which does not take part in bond formation in a molecule is called a nonbonding electron pair.
Example: In the Lewis structure of $H_2O$,the two electron pairs on the $O$ atom are lone pairs,while the two $O-H$ bonds are bond pairs.
Nonbonding electron pair (lone pair): The electron pair which does not take part in bond formation in a molecule is called a nonbonding electron pair.
Example: In the Lewis structure of $H_2O$,the two electron pairs on the $O$ atom are lone pairs,while the two $O-H$ bonds are bond pairs.
