Class 12 Chemistry Aldehydes Ketones and Carboxylic Acids is one of the most important organic chemistry topics in CBSE Class 12 Chemistry and competitive exams like JEE and NEET. The Chapter deals with the structure, properties, preparation, and reactions of aldehydes, ketones, and carboxylic acids.

Organic Chemistry carries around 28-30% weightage in the board exam. Within this NCERT Class 12 Chemistry CH 8 Aldehydes, Ketones, and Carboxylic Acids contributes around 5-8 marks in the CBSE Boards and Other state board exams. 2-3 direct questions (approximately 8-12 marks) appears in JEE Mains from Chapter 8 Class 12 Chemistry.

Alcohols are classified based on the number of alkyl groups attached to the carbon bonded to the –OH group:

• Primary (1°) alcohols has only one alkyl group attached (e.g., Methanol, Ethanol).

• Secondary (2°) alcohols has Two alkyl groups attached (e.g., Isopropanol).

• Tertiary (3°) alcohols has Three alkyl groups attached (e.g., Tert-butanol).

Many students wants to findout that even though phenol and alcohol both contains the hydroxy ion, then why formar is acidic than latter. Well, Here's the answer, Phenols are more acidic because the phenoxide ion formed after losing H? is stabilized by resonance. In contrast, alcohols do not have this resonance stabilization, which make them weaker acids. Students can learn more amazing concepts through visiting NCERT Solutions for Class 12 Chemistry Ch 7 Alcohol Phenol and Ethers.

Alcohols, phenols, and ethers are organic compounds which containd oxygen. Students can check the distict features of these compounds below;

• Alcohols are organic compounds containing the –OH (hydroxyl) functional group attached to a carbon atom.

• Phenols are compounds where the –OH group is directly attached to an aromatic benzene ring.

• Ethers contain an oxygen atom bonded to two alkyl or aryl groups (R–O–R').

Students preparing for the CBSE Board exams must know important topics and type of questions asked from this chapter. Knowing the weightge of Class 12 chemistry chapter 7 alcohol phenol and ether in class 12 board exams helps understanding the importance of the chapter. The Class 12 Chapter 7 alcohol phenol and ether is asked for 6-7 marks in most of the class 12 board exams in india. Students can use NCERT Solutions for Class 12 chemistry chapter 7 alcohol phenol and ethers for studying and practice the questions of the chapter.
