**Summer 2025**

**Question 1:** Chloric acid (HClO<sub>3</sub>) 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 HClO<sub>3</sub>

(b) Use formal charge to determine the **most plausible Lewis structures** of HClO<sub>3</sub>

(c) Predict the **approximate values** for bond angles of HClO<sub>3</sub>

(d) Use **box diagram** to present the hybrid orbital of H, Cl and O in HClO<sub>3</sub>

(e) Indicate **electrons that form σ and π bonds** in the hybrid orbital diagram of each element on in HClO<sub>3</sub>

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