Current Question (ID: 8029)

Question:

Correct statement among the following regarding the shape of $\text{HgCl}_2$, $\text{SnCl}_2$ and $\text{F}_2\text{O}$ is:

Options:

1. All have a linear shape.
2. $\text{SnCl}_2$ are linear and $\text{HgCl}_2$ is V-shaped.
3. $\text{HgCl}_2$ is linear while $\text{SnCl}_2$ and $\text{F}_2\text{O}$ are V-shaped.
4. None of the above.

Solution:

\text{HINT: Hybridisation = sigma bond pairs + lone pairs} \text{Explanation:} \text{HgCl}_2\text{: 2 sigma bonds + 0 lone pairs = sp hybridisation (Linear)} \text{SnCl}_2\text{: 2 sigma bonds + 1 lone pair = sp}^2\text{ hybridisation (V-shape)} \text{F}_2\text{O: 2 sigma bonds + 2 lone pairs = sp}^3\text{ hybridisation (V-shape)} \text{Therefore, option 3 is correct.}
