Current Question (ID: 20995)

Question:

$\text{How many of the following compounds contain a central atom that exhibits } \text{sp}^2 \text{ hybridization?}$ $\text{HCHO, C}_2\text{H}_4, \text{SO}_2, \text{C}_6\text{H}_6, \text{B}_2\text{H}_6, \text{BF}_3, \text{SiO}_2(\text{s}), \text{CH}_2\text{Cl}_2$

Options:

1. $4$
2. $3$
3. $5$
4. $2$

Solution:

$\text{Hint: Steric number} = \frac{1}{2}[V + M - C + A]$ $\text{HCHO} \Rightarrow \text{sp}^2$ $\text{C}_2\text{H}_4 \Rightarrow \text{sp}^2$ $\text{C}_6\text{H}_6 \Rightarrow \text{sp}^2$ $\text{B}_2\text{H}_6 \Rightarrow \text{sp}^3$ $\text{BF}_3 \Rightarrow \text{sp}^2$ $\text{SiO}_2(\text{s}) \Rightarrow \text{sp}^3$ $\text{CH}_2\text{Cl}_2 \Rightarrow \text{sp}^3$ $\text{SO}_2 \Rightarrow \text{sp}^2$ $\text{If steric number is 3, then hybridisation is } \text{sp}^2$
