Aldehydes, Ketones and Carboxylic Acids Class 12 Organic ka sabse important chapter hai — name reactions ka khazana. Yahan aapko is chapter ke sabse important formulas aur quick revision points free milte hain — NCERT/CBSE syllabus ke hisaab se, boards aur JEE/NEET dono ke liye.
Important Formulas & Concepts — Aldehydes, Ketones and Carboxylic Acids
- Rosenmund: RCOCl + H₂/Pd-BaSO₄ → RCHO
- Stephen reduction: RCN + SnCl₂/HCl → RCHO
- Clemmensen: C=O → CH₂ (Zn-Hg/HCl); Wolff-Kishner: (NH₂NH₂/KOH)
- Aldol condensation: alpha-H wale aldehydes/ketones (dil. NaOH)
- Cannizzaro: bina alpha-H wale (HCHO, C₆H₅CHO) — disproportionation
- Tollens test: aldehyde + [Ag(NH₃)₂]⁺ → silver mirror
- Fehling test: aliphatic aldehyde → red ppt (aromatic negative)
- HVZ reaction: carboxylic acid + Cl₂/red P → alpha-chloro acid
Quick Revision Points
- Aldehydes ketones se zyada reactive (steric + electronic)
- Acidity: HCOOH > CH₃COOH; Cl badhao to acidity badhegi
- 2,4-DNP test carbonyl group ki pehchan
- Iodoform: methyl ketones positive
- Carboxylic acid Tollens/Fehling negative — distinguish karna aata hai
