Aldehydes, Ketones & Carboxylic Acids Class 12 | Lecture 2 | Name Reactions & Special Methods

In this Class 12 Chemistry Lecture 2, we continue the NCERT chapter Aldehydes, Ketones and Carboxylic Acids, focusing on important special methods of preparation of aldehydes and ketones, named reactions, and board exam-oriented concepts. In this lecture, Paaji explains important reactions step by step, including the reagents, reaction conditions, mechanisms, limitations, and common mistakes students should avoid while solving organic chemistry conversions. 00:00 – Revision of Common Methods for Aldehyde and Ketone Preparation 02:20 – Special Methods of Aldehyde Preparation: Stephen Reaction 09:04 – DIBAL-H Reduction of Nitriles and Esters 17:01 – Rosenmund Reduction and Its Limitations 27:24 – Preparation of Aldehydes from Toluene: Etard Reaction 36:53 – Gattermann–Koch Reaction: Preparation of Benzaldehyde 39:20 – Preparation of Ketones from Nitriles Using Grignard Reagents 1:18:09 – Oxidation Reactions, Tollens’ Test and Fehling’s Test #PaajiKiKaksha #Class12Chemistry #AldehydesAndKetones #CarboxylicAcids #OrganicChemistry #StephenReaction #RosenmundReduction #EtardReaction #GattermannKochReaction #GrignardReagent #TollensTest #FehlingTest #CBSEBoards2027 #NCERTChemistry #ChemistryLecture
