SATHEE: Chemical Bonding and Molecular Structure

Chemical Bonding and Molecular Structure - Result Question 116

####119. In $N O_{3}^{-}$ ion, number of bond pair and lone pair of electrons on nitrogen atom respectively are

(a) 2,2

(b) 3,1

(d) 4,0

[2002]

Show Answer

Solution:

(d) $N : \frac{↑↓}{1 s^{2}} \frac{↑↓}{2 s^{2}}$

To form $N O_{3}^{-}$ , nitrogen uses one $p$ -electron for $π$ -bond formation and two $p$ -electrons for $σ$ -bond formation. $2 s$ electrons are used for coordinate bond formation. Thus there is no lone pair on nitrogen and four bond pairs are present.
