Which of the following statements regarding hydrides is not correct? — Hydrocarbons Chemistry Question

💡 Solution & Explanation

I need to see the options to provide the specific explanation. However, I can guide you through the key concepts about hydrides that are typically tested: **Common correct statements about hydrides:** - Hydrides are binary compounds of hydrogen with other elements - Ionic hydrides (formed with alkali/alkaline earth metals) are strong reducing agents - Covalent hydrides show varied properties depending on electronegativity - Metallic hydrides have hydrogen in non-stoichiometric ratios - Hydride strength as reducing agent: $\text{ionic} > \text{covalent}$ **Common incorrect statements (likely candidates for option D):** - "All hydrides are covalent" ✗ (ionic hydrides exist) - "Hydrides of non-metals are always ionic" ✗ (they're covalent) - "All hydrides are reducing agents" ✗ (HF is not a reducing agent) - "Hydride ion ($H^-$) exists in all hydrides" ✗ (only in ionic hydrides) - "Stability increases with atomic number in group hydrides" ✗ (decreases: $H_2O > H_2S > H_2Se > H_2Te$) **Please provide the four options (A, B, C, D)** so I can identify exactly which statement is incorrect and explain why D specifically contradicts established hydride chemistry. Once you share them, I'll give a precise answer showing why D is wrong and why A, B, C are correct.
