Current Question (ID: 8041)

Question:

The hybridization of nitrogen in $\text{NO}_2^+$, $\text{NO}_3^-$ and $\text{NH}_4^+$ respectively is :

Options:

1. $\text{sp}$, $\text{sp}^3$, and $\text{sp}^2$
2. $\text{sp}$, $\text{sp}^2$, and $\text{sp}^3$ (Correct)
3. $\text{sp}^2$, $\text{sp}$, and $\text{sp}^3$
4. $\text{sp}^2$, $\text{sp}^3$, and $\text{sp}$

Solution:

$\text{HINT: Find the sum of lone pair and bond pair.}$ $\text{Explanation:}$ $\text{The type of hybrid orbitals of nitrogen can be decided by using VSEPR theory counting bp and as lp in}$ $\text{1. } \text{NO}_2^+ = 2 \text{ bp} + 0 \text{ lp} \Rightarrow \text{sp hybridized.}$ $\text{2. } \text{NO}_3^- = 3 \text{ bp} + 0 \text{ lp} \Rightarrow \text{sp}^2 \text{ hybridized.}$ $\text{3. } \text{NH}_4^+ = 4\text{bp} + 0 \text{ lp} \Rightarrow \text{sp}^3 \text{ hybridized.}$ $\text{Therefore, the correct order of hybridization for } \text{NO}_2^+, \text{NO}_3^-, \text{ and } \text{NH}_4^+ \text{ is } \text{sp, sp}^2, \text{ and sp}^3 \text{ respectively.}$
