Bihar Board - Class 12 Chemistry - Chapter 12: Aldehydes, Ketones and Carboxylic Acids Notes

Chapter Aldehydes, Ketones, and Carboxylic Acids is related to. Students should prepare for the exam by referring to these NCERT notes only. NCERT notes are prepared according to the latest curriculum, and they can help students clarify all their concepts.

Aldehydes and ketones for NCERT notes shed light on important concepts such as the physical properties, nomenclature, and chemical reactions of these compounds. In addition, students can also take tests and mock exams in this chapter to track their progress. This will prove to be very beneficial for students in their exam preparation and help them stay ahead of their peers.

Points to Remember:

• Aldehydes and ketones are prepared by oxidation of alcohols.
• Grignard reagent reacts with cadmium chloride to give dialkylcadmium, which reacts with acyl chlorides to form ketones.
• Both aldehydes and ketones can be prepared by ozonolysis of alkynes.
• Aldehydes without α-hydrogen undergo self-oxidation and decarboxylation (Cannizzaro reaction).
• Carboxylic acids are more acidic compared to alcohols and phenols.

Students in class 12th Science can learn more about NCERT notes for Chapter 12 Chemistry in a subject-specific manner. Thus, students can mention all units for exam preparation.

Subject and Sub-Subject:
