The twelfth board examinations by the Central Board of Secondary Education (CBSE) are going to be held in different cities of the country. This exam will be held from 4 May to 14 June. At the same time, according to the date sheet released by CBSE, the date of examination for the subject of Chemistry (Chemistry) has been fixed for 18 May 2021. That is, students have about two months left to prepare for this topic.
In such a situation, we are starting a special series for you. In which every day, experts will give tips to make a strong preparation according to the subject. In this blog, we will give tips for preparing questions based on organic, inorganic, and physical chemistry. If you are a student of chemistry then this news is very important for you.
The number of objective questions in the question paper of this subject has been reduced from 20 to 16. In this way, the total number of questions will be reduced to 33. Apart from this, two passage-based questions will also be asked in this session (2020-21) in the section on objective questions. Each question will have 4 sub-sections. One digit has been assigned for each sub-part.
Organic chemistry is the most asked question in the board examination. According to the analysis of the last few years, about 28 marks are asked from organic chemistry. At the same time, questions of 19 and 23 marks are asked from Inorganic Chemistry and Physical Chemistry respectively.
In the examination, most of the questions from the Organic Chemistry section are asked through Name Reaction. Many times direct and sometimes indirect questions come from this subject. Therefore, write the name reaction with all the mechanisms in a chart and understand it well. If you understand the name reaction well then the conversion reaction and reaction mechanism will become easy for you.
Electrochemistry, chemical kinetics, liquid solution, and solid-state are the most numerical questions asked in previous years’ paper analysis. Apart from the exercises given in NCERT, the examples given will also have to be read well. Very tough questions are never asked in board exams. The five-digit question is also asked in parts. But to solve them, your concept should be clear. Also, you should remember the formula.
Talk about theoretical questions, they are mostly asked from surface chemistry, coordination compound, D-F block element, and P block element.
