The number of molecules/ions that show linear geometry among the following is ________ $\mathrm{SO}_2,…

The number of molecules/ions that show linear geometry among the following is ________ $\mathrm{SO}_2, \mathrm{BeCl}_2, \mathrm{CO}_2, \mathrm{~N}_3^{-}, \mathrm{NO}_2, \mathrm{~F}_2 \mathrm{O}, \mathrm{XeF}_2, \mathrm{NO}_2^{+}, \mathrm{I}_3^{-}, \mathrm{O}_3$

Solution

\(\begin{array}{ll}
C l-B e-C l & N \equiv N: \rightarrow O \\
\text{sp, linear} & \text{sp, linear}
\end{array}\)
\(\begin{array}{ll}
N^{-}=N^{+}=N^{-} & O=N^{+}=O \\
\text{sp, linear} & \text{sp, linear}
\end{array}\)
like \(I_3^{-}, X e F_2 \rightarrow s p^3 d_1\), Linear
