हिन्दीConsider the following statements regarding the octet rule and its limitations: (A) \( \text{NO} \) and \( \text{NO}_2 \) are odd-electron molecules where the octet rule is not satisfied for all atoms. (B) In \( \text{SCl}_2 \), sulfur disobeys the octet rule by forming an expanded octet. (C) Noble gases like xenon and krypton do not form any chemical compounds under any conditions. (D) The octet theory does not account for the shapes of molecules. How many of the above statements are correct?
Correct answer · Option 2
Only two
Explanation
Only statements (A) and (D) are correct. Statement (B) is false because in SCl2 sulfur obeys the octet rule (8 electrons). Statement (C) is false because Xe and Kr form compounds like XeF2, KrF2.
