Problem 7P
What is the hybridization of nitrogen in each of the following:
(a) NO;
(b) NO2:
(c) NO2−?
ANSWER:
Solution 7P
Here we have to write the hybridization of nitrogen in each of the following molecules.
The hybridization of the central atom can be predicted by knowing the steric number.
Steric number:The hybridization of a molecule can be calculated by using steric number concept of VSEPR theory. The steric number is defined as the sum of a number of atoms bonded to the central atom of a molecule and number of lone pair present on the central atom.
Steric number (SN) = number of bond pair + number of lone pair
According to the VSEPR theory, the relation between hybridization and steric number is shown below,

Step 1
(a) NO
In order to find out the hybridization of NO, we have to draw its Lewis structure.
Steric number (SN) = number of bond pair + number of lone pair
Here the N atom is surrounded by 1 lone pair, 1 bond pair and 1 unpaired electron,
Thus SN = 1 + 1+1 = 3
SN 3 indicates that the hybridization of N in NO is sp2.
Thus the hybridization of N in NO is sp2.
