Summer 2025

Question 1: Chloric acid (HClO₃) is a powerful oxidizer and almost a strong acid. It's used for making chlorate salts.

(a) Regardless of the formal charge, apply octet rule to suggest four (04) possible Lewis structures of HClO₃

(b) Use formal charge to determine the most plausible Lewis structures of HClO₃

(c) Predict the approximate values for bond angles of HClO₃

(d) Use box diagram to present the hybrid orbital of H, Cl and O in HClO₃

(e) Indicate electrons that form σ and π bonds in the hybrid orbital diagram of each element on in HClO₃

Note: You must show all the steps of the problem-solving process.
