Dear students,

With the chemistry 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.

  • Focussing on NCERT questions: The NCERT Part – II comprises of organic chemistry and contributes to 28 marks in the examination.
  • An analysis of previous years’ question papers depicts that many questions are asked as it is from the NCERT textbooks.

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.










Haloalkanes and Haloarenes


Example 10.2 (vi)

Table 10.1

Example 10.7

Example 10.6, 10.17

Ex 10.2 (i)10.9 (i), 10.14 (vii)

Exercise 16.10


16.21 (i)

16.15, 16.17, 16.21 (i)

16.12, 16.22


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

  • IUPAC Nomenclature questions: A conclusion from previous years’ papers is that, 90% of the questions related to nomenclature of organic compounds usually come from the tables of common and IUPAC names or in-text examples present in NCERT book. Below is a summarized chart of all the tables and in-text examples meant for nomenclature.
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.

  • Name reactions: Important name reactions which have been asked previously are Sandmeyer reaction, Williamson synthesis, Riemer-Tiemann reaction, Kolbe’s reaction, Aldol Condensation, Cannizzaro Reaction, Clemmensen Reduction reaction, Hoffmann Bromamide reaction, Coupling reaction. So,we advise you to revise these reactions.
  • Distinction test: The distinction tests are usually asked between:
  • Aliphatic and aromatic compounds
  • Compounds having two different functional groups
  • Compounds having same functional group but different arrangement of atoms (e.g., 1°, 2°, 3°)

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.

  • Conversions: Conversion based questions are surely going to come in exams. Remember there can be multiple steps to reach the final product but the shortest and feasible steps have to be written in the answer-sheet.

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 2014

Unit Expected areas from where questions can be asked in 2014 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 Distinction Tests Named Reaction in Detail and Named Reaction List.

Follow these simple but smart ways and give your 100 % in the examination.

Best of Luck!
