The correct statement(s) regarding,
(i) `HClO`, (ii) `HClO_(2)`, (iii) `HClO_(3)` and (iv) `HClO_(4)` is (are)

Options

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 hydridizatio of Cl in (iv) is `sp^2`.
D. Amogst (i) to (iv), the strongest acid is (i).

Answer

B

Explanation

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 `sp^(3)`
Strongest acid is `HClO_(4)` (iv).
