Question

The correct statement(s) regarding, (i) $HClO$, (ii) $HCl{O}_2$, (iii) $HCl{O}_3$ and (iv) $HCl{O}_4$ is(are):

• A. The number of $Cl=O$ bonds in (ii) and (iii) together is two
• B. The number of lone pairs of electrons on $Cl$ in (ii) and (iii) together is three
• C. The hybridization of $Cl$ in (iv) is $s{p}^3$
• D. Amongst (i) to (iv), the strongest acid is (i)

Answer 1

Answer: (B), (C)

The correct options are
B The number of lone pairs of electrons on $Cl$ in (ii) and (iii) together is three
C The hybridization of $Cl$ in (iv) is $s{p}^3$


The number of $Cl=O$ bonds in (ii) and (iii) together is three.
Number of lone pairs on $Cl$ in (ii) and (iii) together is three.
Hybridisation of $Cl$ in (iv) is $s{p}^3$.
Strongest acid is $HCl{O}_4$ (iv).
