The correct statement(s) about the oxoacids, HClO₄ and HClO, is(are)
[A] HClO₄ is more acidic than HClO because of the resonance stabilization of its anion
[B] HClO₄ is formed in the reaction between Cl₂ and H₂O
[C] The central atom in both HClO₄ and HClO is sp³ hybridized
[D] The conjugate base of HClO₄ is weaker base than H₂O

Answer:
HELLO!!!!
The correct statement(s) about the oxoacids, HClO
4
and HClO, are the following
(A) The central atom in both HClO
4
and HClO is sp
3
hybridized. The central Cl atom in HClO
4
has 4 bonding domains and zero lone pairs of electrons.
The central O atom in HClO has 2 bonding domains and 2 lone pairs of electrons.
(B) The conjugate base of HClO
4
is weaker base than H
2
O. This is because HClO
4
is stronger acid than water. A stronger acid has weaker conjugate base and vice versa.
(D) HClO
4
is more acidic than HClO because of the resonance stabilization of its anion. Greater is the extent of delocalisation, greater is the stabilisation of negative charge and higher is the acidity. In HClO
4
, negative charge is delocalised over 4O atoms.
The following statement is incorrect.
(C) HClO
4
is formed in the reaction between Cl
2
and H
2
O."
Instead, the following methods are used.
NaClO
4
+HCl→NaCl+HClO

Laboratory preparations of HClO
4
include the following
Treatment of barium perchlorate with sulfuric acid to give barium sulfate and perchloric acid.
Nitric acid is mixed with ammonium perchlorate to form nitrous oxide and perchloric acid
