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

💡 Solution & Explanation

I need to see the options to provide a proper analysis. Since you've indicated the correct answer is D but haven't provided the options, I'll outline the typical incorrect statements about hydrides: **Common misconceptions about hydrides:** **Statement types that are often INCORRECT (likely option D):** 1. **"All hydrides are covalent"** — WRONG. Some hydrides are ionic (like $NaH$, $CaH_2$) 2. **"Hydride ion ($H^-$) is formed by loss of an electron from hydrogen"** — WRONG. $H^-$ forms by *gaining* an electron, not losing it 3. **"Hydrides of group 16 elements are stronger acids than group 17 hydrides"** — WRONG. $HCl, HBr, HI$ are much stronger acids than $H_2O, H_2S, H_2Se$ 4. **"Hydrides are always more stable at higher temperatures"** — WRONG. Many hydrides decompose at high temperatures 5. **"Metallic hydrides conduct electricity"** — WRONG. Most are insulators in solid state **Without seeing option D specifically, the most likely incorrect statement involves:** - Confusing formation mechanism of $H^-$ (gaining vs. losing electrons) - Incorrectly ranking acid strength or thermal stability - Wrongly classifying all hydrides as covalent or metallic **Please provide the options so I can give the exact reasoning for why option D is incorrect.**
