Students should note that all topics are important and should be reviewed. However, in case you missed any part of the program earlier, now may not be the right time to study it.

CBSE Class 12 Chemistry: Review Guidelines

  1. Read notes carefully and write down all reactions: It’s a common mistake students make when they just memorize reactions and don’t write them down. Writing down reactions helps you remember them well. Students can try this trick – Open the chapter of your NCERT books and start writing the reactions of each of them just by remembering the topics you studied in that chapter.
  2. Do not try to study any book other than the NCERT: do you know that half of the article is just a simple copy of your NCERT book? You may not want to accept it, but the questions in the theory part are strictly based on the NCERTs.
  3. Do not panic in case you have missed a chapter or a subject: it is not possible to waste your time just before the exam. Just because your friend has finished a certain chapter or is ahead of you in review doesn’t mean you’re not studying well or preparing well.

CBSE Class 12 Chemistry: Techniques for Writing Answers for a 90% Score

Students in CBSE Class 12 should try to write short, crisp answers in their science exam papers. Chemistry is a subject that demands straight and direct answers. You must at all times support your answers with a quick reaction or diagram.

Try to write the answers according to the scoring scheme provided with each question. If a question is worth 2 points, in no case write more than 25 words.

Also, try not to waste time if you don’t know the answer. Always skip to questions you know the answer to.

Solve the following questions to check your knowledge:

  1. Count the following:
  1. Propanol has a higher boiling point than butane.
  2. Ortho-nitrophenol is more acidic than ortho-methoxyphenol.
  3. The preparation of ethers by acid dehydration of secondary or tertiary alcohols is not a suitable method.

2. The conductivity of metals decreases while that of electrolytes increases with an increase in temperature. Why?

3. The conductivity of an aqueous solution of NaCl in a cell is 92 Ω-1 cm -1 the resistance offered by this cell is 247.8 Ω. Calculate the cell constant?

4. Calculate the emf of the next cell Cd /Cd2+ (0.10 M)//H+ (0.20 M)/H2 (0.5 atm) /Pt

[Given E° for Cd2+ /Cd = -0.403V]

5. Can a galvanic cell act like an electrolytic cell? How?

6. (A). What is an electrochemical series? How does it predict the feasibility of a certain redox reaction?

(B). The arrangement of metals and ions in ascending order of their electrode potential values ​​is known as the electrochemical series. The reduction half reaction for which the reduction potential is lower than the other will act as an anode and the one with greater value will act as a cathode. A reverse reaction will not occur.

7 (A) The radioactive decay half-life of14It is 5730 years. An archaeological artefact containing wood had only 80% of the14C found in a living tree. Estimate the age of the sample.

(B) Is the action first-order in A and second-order in B.

Write the differential rate equation. How is the rate affected by increasing the concentration of B three times? How is the rate affected when the concentrations of A and B are doubled?
