Hint: In chemistry, a lone pair of electrons means a pair of valence electrons that are not shared with another atom at the formation of a covalent bond and is occasionally called an unshared pair or non-bonding pair.
Complete step by step answer:
- Lone pairs are found in the outermost electron shell of atoms.
- Lone pair of electrons can be identified by using a Lewis structure.
- The Lewis structure of the given molecule is as follows.
- In Lewis structure the lone pair of electrons denoted on the respective atoms is very clear. So, we can count them very easily by using Lewis structure.
- Now, coming to given options, option A, 2. It is wrong because the given molecule contains more than two lone pairs of electrons in its structure.
- Coming to option C, 4. It is wrong because the given molecule contains less than four lone pairs of electrons in its structure.
- Coming to option D, 5. It is wrong because the given molecule contains less than four lone pairs of electrons in its structure.
- Coming to option C, 3. Yes the given molecule contains three lone pairs of electrons. Two lone pairs on oxygen atoms and one lone pair on nitrogen atoms.
So, the correct option is C.
Note: Don’t be confused with the terms non-bonding electrons and lone pair of electrons. Both are the same.
Lone pair of electrons: the electrons which do not involve in bonding with other atoms are called lone pairs of electrons.
