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 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 electrons on Cl in (ii) and (iii) together is three.
C The hybridization of Cl in (iv) is $s{p}^3$


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