With the exams approaching, your preparation must be at its peak. It is a general myth among the students that organic chemistry is the toughest topic to score marks in, however this is not the case. With only a few days left before the examination, the team of chemistry experts at Meritnation bring to you some really beneficial strategies to master this portion of the syllabus.
The table given below shows the exact question numbers of the questions in the NCERT book which have been asked in the examination. Note that, many questions are being asked repeatedly.
| Units | Marks | 2011 | 2010 | 2009 | 2008 | 2007 | 2006 |
| Haloalkanes and Haloarenes | 4 | Table 10.1 | Example 10.7 | Example 10.6, 10.17 | Ex 10.2 (i)10.9 (i), 10.14 (vii) | – | – |
| Alcohols, Phenols and Ethers | 4 | 11.18 (ii), 11.31 (iv) |
11.20 (ii, iv), 11.18 (i, iii) | 11.3 (v) | 11.3 (ii), 11.21 (ii, ii, vi) | 11.22 | – |
| Aldehydes, Ketones and Carboxylic Acids | 6 | 12.13 (i, iv), 12.16 (ii, iv), 12.17 (i, ii) |
Fig 12.2, 12.11, 12.13 (iii, vii), 12.12 (i, ii) | 12.16 (ii), 12.19, 12.17 (iv) | 12.12 (ii), 12.17 (i, x, xi), 12.16 (ii, iii) | Table 12.1, 12.13 (i) | 12.16 (ii), 12.13 (vii) |
| Amines | 4 | 13.4 (ii) |
Table 13.1, 13.4 (i,ii, iii-a, iv) | Ex 13.4, 13.7 (iii, iv) | 13.3 (I, iii, v) | 13.12 | 13.2 (v) |
| Biomolecules | 4 | 14.12, 14.13 |
14.17, 14.22 | 14.12 (i), table 14.3 | 14.12 (i, iii), 14.10 | 14.12 (ii) | 14.15, table14.3 |
| Polymers | 3 | 15.2 |
15.11 | 15.12 | 15.17 | 15.12, 15.16 | 15.12, 15.15 |
| Chemistry in Everyday Life | 3 | 16.15 |
16.21 (i) | 16.15, 16.17, 16.21 (i) | 16.12, 16.22 | 16.15 | – |
So, mark these questions in the NCERT book and go through all the NCERT solutions thoroughly. For this you can also refer to the NCERT solutions section on meritnation.com
| Haloalkanes and Haloarenes | Table 10.1, example 10.1 and example 10.2 |
| Alcohols, Phenols and Ethers | Table 11.1, 11.2, example 11.1 and in-text question 11.3 |
| Aldehydes, ketones and carboxylic acids | Table 12.1 and intext questions 12.1, Table 12.3 and in-text question 12.6 |
| Amines | Table 13.1 |
Note: Do not leave even a single compound from the tables and in-text examples.
Steps for attempting these questions
Step – I: See how many marks are allotted to the question. Remember, 1 mark is for 1 test.
Step – II: Write the structural formulae of both the compounds.
Step – III: See where the two structures differ in.
Step – IV: Recall the reactions which you have studied.
Step – V: Apply those reactions in the compounds keeping in mind the skeletal structure they differ in.
Please note CBSE has yet not asked any conversion which consist of more than 3-steps.
Steps for attempting these questions
Step – I: Read the question very carefully.
Step – II: Write the starting compound on the left hand side and the final compound on the right hand side.
Step – III: See where do the two structure differ in.
(They mostly differ either in functional groups, number of carbon atoms or both)
Step – IV: Recall the reactions which you have studied.
Step – V: Apply those reactions in initial compound so as to reach to the final compound.
Expected areas from where questions can come in 2012
| Unit | Expected areas from where questions can be asked in 2012 examination |
| Haloalkanes and Haloarenes | IUPAC Nomenclature, SN1 and SN2 reaction (Question: Which compound undergoes faster reaction?), DDT, Iodoform |
| Alcohols, Phenols and Ethers | IUPAC Nomenclature, Conversions, Alcohols – Boiling points and solubilities, Phenols-Acidic properties, Difference in the boiling points of ethers and alcohols, Williamson reaction, Reimer-Tiemann reaction |
| Aldehydes, Ketones and Carboxylic Acids | IUPAC Nomenclature, Nucleophilic addition on carbonyl carbon, Aldol Condensation, Cannizzaro reaction, Clemmensen reduction reaction, Acidity of carboxylic acids (Question: Arrange the following compounds in increasing/ decreasing order of their acidic trends.), Distinction tests, Conversions |
| Amines | IUPAC Nomenclature, Basicities of amines (Question: Arrange the following amines in increasing/ decreasing order of their basic strengths.), Hoffmann Bromamide reaction, Coupling reaction, Aniline -Insoluble in water and does not undergo Friedel Crafts reaction |
| Biomolecules | Glucose open chain and cyclic structure (Question: Why was the open chain structure of glucose unable to explain its properties?), Proteins-Primary, secondary, tertiary and quarternery structures, Vitamins – Sources and deficiency disease – table 4.3, nucleosides and nucleotides |
| Polymers | Elastomer, thermoplastic and thermosetting polymer, Rubber, Nylon 6, nylon 6,6, teflon, bakelite, Buna-N |
| Chemistry in Everyday Life | Detergents, Food preservatives, Enzymes, Antifertility drugs, Analgesics, Artificial sweetening agents, biodegradable and non-biodegradable detergents |
To help all you students in these last stage of preparation, we are providing Conversion Schemes and Distinction Tests
Follow these simple but smart ways and give your 100 % in the examination.
Best of Luck!
