Mnemonics to prepare for Chemistry Section

Last Updated - May 05, 2018

Students appearing for NEET must be aware of the exam pattern and syllabus. Preparation is in full swing as students solve practice papers and go over the syllabus. NEET 2018 will be conducted on May 6, 2018.

Mnemonics are fun learning tools that creates an association of complex theory or formulae with ordinary items or activities and helps in memorizing concepts. Common mnemonics are short poems, phrases or acronyms that allows easy memory recall.

Students in preparation for NEET can use some cool mnemonics to commit to memory the huge load of concepts that, particularly, Chemistry syllabus has. In this section, we list some popular mnemonics that students can resort to jazz up their NEET Chemistry Prep.

  • Sequence of atomic orbitals: Sober Physicists Don’t Find Giraffes Hiding In Kitchens. (After the k shell, they follow alphabetical order (skipping s and p as they came earlier).

NEET Chemistry Paper Analysis

The chemistry section of NEET 2018 will have 45 multiple-choice questions, with a total maximum score of 180 marks; each correct answer carrying 4 marks while each wrong answer attracting a penalty of -1 mark. Questions that are not attempted or questions with two options marked as answer will be awarded 0. Since the exam is an offline one, students will have to mark their answers properly in an OMR sheet with blue/black ball point pen. Read More AboutNEET 2018 Paper Analysis.

  • NEET 2017 question paper posed more number of questions from Organic Chemistry than Inorganic Chemistry, breaking the pattern of many years.
  • Examinees were of the opinion that the questions covering class XI syllabus were not very tough but the ones from class XII syllabus were very tricky.
  • The questions were mostly conceptual and candidates were to apply their knowledge of basic concepts to solve problems in the paper.

An analysis of past NEET question papers reveal that s-block, p-block, d-block & f-block are the common topics while special reactions in organic chemistry also deserve a special mention. Given the trend set by NEET 2017, students appearing for NEET 2018 should expect maximum number of question from Organic Chemistry. Experts suggest that the following topics be given precedence at the time of exam preparation.

  • Organic Chemistry
  • Coordination Compounds
  • Chemical Bonding
  • Carbonyl Compounds

Here follows an expected topic-wise most frequently asked questions and their corresponding percentage in NEET Chemistry.
