Q. According to the concept of resonance, whenever a single Lewis structure can't describe a molecule accurately, then a number of structure called resonating structure, with similar energy. Same relative position of all nuclei and with same number of paired and unpaired electrons The molecule as such has a single definite structure which is the resonance hybrid of the resonating structure and can't as such be depicted by a single Lewis structure. As a result of resonance, the bond order may change in many molecules or ions, and is given by formula
Total number of bonds between two atoms
Bond order $=\frac{\text { in all the structure }}{\text { Total number of resonating structures }}$
Which of the following molecule contains one pair of non bonding electrons?

Chemical Bonding and Molecular Structure

Solution:

In $NH _3$ nitrogen has one lone pair of electron
