The order of CO bond strength in the following metal hexacarbonyls is likely to be:
Explanation
CO bond strength is determined by metal-to-ligand backbonding. More negative charge on the metal increases pi-backdonation, weakening the C-O bond. Thus, V(CO)6^- has the weakest C-O bond, and Mn(CO)6^+ has the strongest C-O bond.
دھات پر جتنا زیادہ منفی چارج ہوگا، بیک بانڈنگ زیادہ ہوگی اور C-O بانڈ کمزور ہوگا۔ اس لیے CO بانڈ کی طاقت کی صحیح ترتیب: V(CO)6^- < Cr(CO)6 < Mn(CO)6^+ ہے۔

پی ایچ (pH) اسکیل 0 سے 14 تک ہوتا ہے۔ 7 سے نیچے تیزابی خصوصیات ہوتی ہیں، اور پی ایچ جتنا کم ہوگا تیزابیت اتنی ہی مضبوط ہوگی۔ یعنی پی ایچ 2 سب سے تیز ہے۔
