Why Cu+ is Unstable? 🧪 The Mystery of Copper Disproportionation & Redox Reactions🔥

⚡ Mastering Copper Chemistry: Oxidation States, Disproportionation & Medium Effects 🧪 Welcome to Subatomic Duo ! In this comprehensive lecture, we dive deep into the d-block chemistry of Copper (Cu). We don't just memorize reactions here—we track the movement of every single electron to understand why these transformations happen. Whether you are preparing for IIT-JEE, NEET, or University exams, this video is your definitive guide to Copper’s redox behavior and its essential compounds. Chapters: 0:00 - Introduction of Copper as an Element and it's oxidation states 04:03 - Introduction of Cu+ ( Color, electronic configuration) 07:54 - Stability Paradox ( Why Cu²+ is more stable in aqueous solution) [ Key Concept ] 🔥🔥🔥 10:34 - Thermodynamics of Cu+ ( Born Haber cycle of Cu+ ) 18:00 - Thermodynamics of Cu²+ ( Born Haber cycle of Cu²+ ) 22:40 - Thermodynamics of Disproportionation Reaction or Why Cu²+ is hightly stable in an aqueous solution and concept of " "hydration Energy "( Key Concept) 🔥🔥🔥 28:17 - How to stabilize Cu+ in Aqueous solution. 32:10 - How to destabilize Cu²+ in aqueous solution ( Concept of Lattice energy) 🔥🔥 39:35 - Comproportionation Reaction 42:55 - Why CuF does not exist? 47:21 - Why CuI does not exist? 49:50 - Stabilization of Cu+ in non aqueous solvents 51:15 - Reaction of Cu+ with Cyanide ion ( Formation of potassium tetracyano copper complex ) 53:58 - Stabilization of Cu+ by complexation 55:15 - Complexation of Copper Sulfate with KCN 01:01:05 - Cyanogen gas ( Chemical warfare agent or Blood Agent ) 🔥🔥 01:02:40 - Cellular Respiration 🔥 01:05:00 - Effect of Cyanogen gas on human body 01:06:11 - First and second hottest flames 01:08:50 - Behaviour of Cu+ in Neutral Water/ Acidic Solution 01:09:51 - Behaviour of Cu+ in Basic Solution ( Formation of cuprous oxide Lattice) 01:12:31 - Basic introduction of Cu²+ ion , explanation of color 01:15:11 - Behaviour of cu²+ in Neutral Water 01:17:00 - Behaviour of Cu²+ in Acidic Solution ( Sulphuric Acid ) 01:18:37 - Behaviour of Cu²+ with Hydrochloride acid. 01:21:07 - Behaviour of Cu²+ in Basic Solution 01:24:57 - Reaction of Copper (II) Hydroxide with Ammonia or Formation of tetraamminecopper(II) ion 01:29:45 - Reaction Of Copper With Hydrochloride Acid 🔥🔥 01:34:17 - Reaction of Copper with dilute Nitric Acid 01:38:47 - Reaction of Copper with Conc. Nitric Acid 01:39:57 - Reaction of Copper (II) Oxide with Hydrochloric Acid 01:40:47 - Reaction of Copper (I) Oxide with Hydrochloric Acid 🔍 Key Concepts Covered: 1. The Cu(I) vs Cu(II) Stability Paradox Why is Cu²+ (3d⁹) more stable in an aqueous solution than Cu+ (3d¹⁰)? We break down the competition between Second Ionization Enthalpy and Hydration Enthalpy. 2. Disproportionation of Cu(I) We analyze the spontaneous self redox reaction that occurs in water: 2Cu+ ➡️ 2Cu²+ + Cu (s) The Electron Move: One Cu+ ion loses an electron (Oxidation) to become Cu²+ while another Cu+ ion accepts that electron (Reduction) to become metallic Cu⁰. Stability: Why does this happen in acidic/neutral media but change in the presence of specific ligands? 3. Behavior in Different Media: 🔥Acidic Medium/Neutral Medium: Stability of Cu²+ and the immediate disproportionation of Cu+. 🔥 Basic Medium: Formation of Cu(OH)2 (pale blue ppt) and its dehydration to CuO (black). 🔥 Ammoniacal Medium: The formation of the deep blue [Cu(NH3)4]²+complex. 4. Crucial Reactions of Copper Compounds Reaction with HNO3 (Dilute vs. Conc.): Tracking the change in Nitrogen's oxidation state from +5 to +2 or +4 ( NO or NO2 ) 🔥We also cover the most important reactions of copper and its compounds, including: Reactions of CuSO₄, CuCl₂, Cu₂O, CuO 📚 Join " Subatomic Duo" Community: If you want to master chemistry through logic rather than rote learning, Subscribe and hit the bell icon!
