Examination Structure and Guidelines

The Class 12 Half-Yearly Chemistry model paper is set for a total duration of 3 hours and 15 minutes. Of this time, the initial 15 minutes are specifically allotted for examinees to read the question paper thoroughly before attempting any answers. The maximum marks for the paper are 70, aligning with the standard assessment pattern for the subject.

The question paper code for this model is 347. Students are advised to adhere to the time distribution, ensuring they utilise the reading time effectively to strategise their approach to the examination.

Key Topics Covered in the Model Paper

The model question paper encompasses many topics from the Class 12 Chemistry syllabus. It includes theoretical concepts as well as application-based questions, covering both physical and organic chemistry. Students will find questions on fundamental principles and their practical implications.

Specific areas addressed in the paper include protein solutions, osmotic pressure, and the conversion of cumene to phenol. Questions also explore the uses of aldehydes and ketones, and the structure of DNA bases. Distinctions between ideal and non-ideal solutions, plus hypertonic and hypotonic solutions, are also part of the assessment. The paper further explores fuel cells, their electrode reactions, and the catalysts employed, alongside the temperature dependence of reaction rates. Other topics include the stability of Cu+ ions in aqueous solution, comparing the reducing power of Cu2+ and Fe2+, and crystal field splitting in tetrahedral coordination complexes. Calculations for molar conductivity and the dissociation constant of acetic acid are also featured. The paper asks for names and descriptions of two classes of proteins based on molecular shape, and requires graphs related to zero-order reactions, first-order reactions, and the Arrhenius equation. Reasons for solubility differences between ethylamine and aniline, and the stability of diazonium salts are also asked. The paper includes questions on Friedel-Crafts reaction and various organic conversions, such as propene to propan-2-ol and benzyl chloride to benzyl alcohol. Named reactions like Kolbe’s reaction, Reimer-Tiemann reaction, and Williamson ether synthesis are covered. A passage on carboxylic acids is provided, followed by questions based on it. Questions involve identifying organic compounds (A, B, C) from an alkene’s ozonolysis and subsequent reactions, and asks about the products formed when various organic compounds react with specific reagents.
