The correct Answer is:
To solve the question, we need to analyze the similarities between hydrogen and alkali metals in terms of the compounds they can form. Let's break down the options step by step. ### Step-by-Step Solution: 1. **Understanding Hydrogen and Alkali Metals:** - Hydrogen has an electronic configuration of 1s¹, which means it has one electron in its outer shell. - Alkali metals (like lithium, sodium, potassium) also have a single electron in their outermost shell (ns¹). 2. **Formation of Ions:** - Both hydrogen and alkali metals can lose one electron to form a unipositive ion (H⁺ for hydrogen and M⁺ for alkali metals). 3. **Analyzing the Statements:** - **Statement I: Oxides and Oxyacids** - Hydrogen can form oxides (like H₂O) but does not typically form oxyacids in the same way that alkali metals do. Therefore, this statement is **incorrect**. - **Statement II: Halides and Interhalides** - Hydrogen can form halides (like HCl), but it does not form interhalides (compounds formed between halogens and other halogens). Thus, this statement is also **incorrect**. - **Statement III: Oxides, Halides, and Sulphides** - Hydrogen can indeed form oxides (H₂O), halides (HCl), and sulfides (like H₂S). This statement is **correct**. 4. **Conclusion:** - The only correct statement is Statement III, which indicates that hydrogen forms oxides, halides, and sulfides, similar to alkali metals. ### Final Answer: The correct option is **III: Oxides, Halides, and Sulphides**.
