Question

Which of the following option is correct about $N{O}_2$ and $Cl{O}_2$?

(i) Both are paramagnetic species

(ii) Both compounds dimerised readily

(iii) Both have $s{p}^2$ hybridisation

(iv) Both have bent shape.

• A. (i) ,(ii)
• B. (i), (iii), (iv)
• C. (ii) , (iii), (iv)
• D. only (i)

Answer 1

Answer: (B)

(i), (iii), (iv)

$N{O}_2$ is $s{p}^2$ hybridized

(Image 1)

It has $1$ unpaired electron, so paramagnetic shape of $N{O}_2$ is bent and it dimerises easily.

$Cl{O}_2$

(Image 2) has $s{p}^2$ hybridization

and the $Cl{O}_2$ and is bent shape and $Cl{O}_2$ do not dimerise because $Cl{O}_2$ has vacant d-orbital.
