To understand it better, first, we will calculate the oxidation state of HCl, HClO4, and KClO3.
The oxidation state of chlorine in HCl will be
1 + x = 0
x = – 1
The oxidation state of chlorine in HClO4 will be:
1 + x + 4 X ( -2) = 0
1 + x – 8 = 0
x – 7 = 0
x = + 7
The oxidation state of chlorine in KClO3 will be
1 + x + 3 X ( -2 ) = 0
1 + x – 6 = 0
x = + 5
Hence the oxidation state of chlorine is maximum in HClO4, i.e. equivalent to + 7.
The oxidation state of chlorine in HCl will be
1 + x = 0
x = – 1
The oxidation state of chlorine in HClO4 will be:
1 + x + 4 X ( -2) = 0
1 + x – 8 = 0
x – 7 = 0
x = + 7
The oxidation state of chlorine in KClO3 will be
1 + x + 3 X ( -2 ) = 0
1 + x – 6 = 0
x = + 5
Hence the oxidation state of chlorine is maximum in HClO4, i.e. equivalent to + 7.

In which of the following compound will chlorine show the highest oxid...
Explanation:
Chlorine can exhibit different oxidation states depending on the compound it is present in. The highest oxidation state of chlorine is +7, and it is found in compounds where chlorine is bonded to highly electronegative elements such as oxygen.
Analysis of options:
a) HCl: In hydrochloric acid (HCl), chlorine is in the -1 oxidation state. This is because hydrogen has an oxidation state of +1, and the overall charge of the compound is 0. Chlorine is more electronegative than hydrogen, so it takes the negative oxidation state of -1.
b) HClO4: In perchloric acid (HClO4), chlorine is in the +7 oxidation state. This is because oxygen is highly electronegative, and each oxygen atom in the molecule contributes -2 to the overall charge. The hydrogen atom has an oxidation state of +1, so chlorine must have an oxidation state of +7 to balance the charges. Therefore, chlorine shows the highest oxidation state in HClO4.
c) KClO3: In potassium chlorate (KClO3), chlorine is in the +5 oxidation state. This is because oxygen contributes -2 to the overall charge, and potassium has an oxidation state of +1. Chlorine must have an oxidation state of +5 to balance the charges.
d) None of the above: The only compound in the given options where chlorine shows the highest oxidation state is HClO4 (perchloric acid). Therefore, the correct answer is option B.
Summary:
Chlorine shows the highest oxidation state of +7 in perchloric acid (HClO4) because it is bonded to highly electronegative oxygen atoms. In the other compounds, chlorine has lower oxidation states.
