Question

In HCIO3 molecule, chlorine is present in which state​

Answer 1

Explanation:

+5

Hence, the oxidation state of Cl in HClO3 is +5.

Answer 2

The complete question is:

In HClO3 molecule, chlorine is present in

a. ground state

b. first excited state

c. second excited state

d. third excited state ​

The correct option is option a, i.e. ground state.

• Since the hybridization of chlorine in chloric acid i.e. HClO3 is sp³, therefore it is in ground state.
• Chlorine has three binding partners i.e. oxygen and one pair of lone pair of electrons. The molecule has three identical Cl-O bonds, each intermediate between single and double.
• Chlorine has a formal charge of +2 in HClO3.
