Solved NCERT Questions For Class 12 Chemistry Chapter 14 In Hindi - Free PDF
FAQs on NCERT Solutions For Class 12 Chemistry Chapter 14 Biomolecules in Hindi - 2025-26
1. What approach should students follow when using NCERT Solutions for Class 12 Chemistry Chapter 14 to answer CBSE-style questions?
Begin by reading the textbook section carefully, then refer to the stepwise solutions for each exercise. Focus on understanding the core concept behind every step, mirror the CBSE marking scheme in your written answers, and present final answers in a structured format with relevant chemical equations and diagrams where required.
2. How do NCERT Solutions for Biomolecules help clarify differences between carbohydrates, proteins, and nucleic acids?
The solutions break down each biomolecule class into
- Carbohydrates: focus on structure and energy roles
- Proteins: highlight amino acid linkage and function
- Nucleic acids: explain genetic storage and transfer
3. What is the correct stepwise method to solve a question on classification of biomolecules as monosaccharide or disaccharide using NCERT Solutions?
First, list all given compounds. Next, recall the definitions: monosaccharides are single sugar units, while disaccharides contain two monosaccharides joined by a glycosidic bond. Then, match each compound to its class based on structural knowledge provided in the solution steps.
4. Why is it important to highlight the type of bond, such as peptide or glycosidic, when answering protein and carbohydrate structure questions?
Mentioning the specific bonds demonstrates a deeper understanding expected in board answers and is often directly linked to exam questions. Proper identification also helps in accurately representing structure and biological function, which is a key CBSE evaluation criterion.
5. How can NCERT Solutions help students avoid common mistakes in reaction mechanisms involving biomolecules, such as hydrolysis of sucrose or denaturation of proteins?
The solutions provide a stepwise breakdown of each reaction: writing correct chemical equations, showing bond changes, and identifying products. This approach teaches students to avoid errors like omitting water in hydrolysis or mislabeling the roles of reactants and catalysts, supporting accuracy in exam settings.
6. What are the benefits of following the sample chemical equations as given in the NCERT Solutions for Class 12 Chemistry Chapter 14?
- Ensures answers are CBSE compliant for marks
- Improves clarity in representing organic reactions
- Helps students remember correct reactant-product relationships
- Prepares students to write equations confidently in exams
7. Why do stepwise NCERT Solutions emphasize molecular diagrams and structural formulas, and how do they aid exam performance?
Diagrams and structural formulas visually reinforce concepts such as ring structures, bond types, or functional group positions. In board exams, well-labeled diagrams can fetch extra marks and help in clear presentation, as recommended by CBSE marking schemes.
8. How should a student approach a question about the difference between DNA and RNA using the method shown in NCERT Solutions?
First, state the fundamental differences using a tabular or bulleted format as modeled in the solutions: list sugar type, base composition, roles, and structure. Clear, direct contrasts such as 'deoxyribose vs ribose' and 'thymine vs uracil' are essential for full marks.
9. What should students do if they have a conceptual doubt while solving NCERT Solutions for Class 12 Chemistry Chapter 14 Biomolecules?
They should revisit the relevant CBSE textbook section and cross-reference the stepwise solution to trace the logic applied. If confusion persists, break down the question into smaller parts and check each step to find where the misunderstanding occurred, aligning with the detailed methodology given in solutions.
10. How can understanding the answers in NCERT Solutions for Biomolecules help in tackling higher-order thinking questions in CBSE exams?
Detailed, step-by-step answers build a solid conceptual base, empowering students to apply learned logic to unfamiliar problems, make connections across topics, and justify each step logically—skills that are critical when facing HOTS (Higher Order Thinking Skills) questions in board exams.
