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. (Correct)
  • 4. None of the above.
Solution:
$\text{HINT: Hybridisation can be calculated by number of sigma bond pairs and lone pairs.}$ $\text{Explanation:}$ $\begin{tabular}{|l|l|l|l|l|} \hline \text{Molecules} & \text{$\sigma$ bond pair} & \text{Lone pair} & \text{Hybridisation} & \text{Shape} \\ \hline \text{HgCl}_2 & 2 & 0 & \text{sp} & \text{Linear} \\ \hline \text{SnCl}_2 & 2 & 1 & \text{sp}^2 & \text{V-shape} \\ \hline \text{F}_2\text{O} & 2 & 2 & \text{sp}^3 & \text{V-shape} \\ \hline \end{tabular}$ $\text{So, option 3 is the correct answer.}$
