NEET 2023 Chemistry: Chapter-Wise Weightage

The following table shows the different chapters students need to prepare for the NEET 2023 Chemistry exam along with the weightage of each chapter.

 

Synopsis of Chemical Bonding and Molecular Structure

  • The attraction force that holds varied constituents (atoms and ions) in different chemical species together is known as the chemical bond.

  • Every atom seeks to achieve the octet configuration (presence of eight electrons) in its valence shell by losing, gaining, or sharing electrons, according to the electrical theory of valence. This is what we call the octet rule.

  • Symbols of Lewis- Lewis invented the concept of portraying valence electrons with dots, which are known as Lewis symbols, to help people grasp the concept of valence electrons.

  • The electrovalent bond is the bond created when positive and negative ions are attracted to each other by electrostatic attraction. The number of unit charge(s) on the ion equals the electrovalence.

  • A covalent bond occurs when two identical or dissimilar atoms share their valence electron to achieve the noble gas state.

  • The difference between the number of valence electrons of an atom in an isolated or free state and the number of electrons assigned to that atom in the Lewis structure may represent the formal charge of an atom in a polyatomic molecule or ion.

  • Hybridization is the process of combining two atomic orbitals of the same energy level to create a degraded new type of orbitals. Bond Length- The equilibrium distance between the nuclei of two bound atoms in a molecule is called bond length.

  • The bond angle is the angle created by the orbitals containing bonding electron pairs surrounding the central atom in a molecule/complex ion.

  • Bond Enthalpy- The amount of energy required to break one mole of a specific type of bond between two atoms in a gaseous state is known as bond enthalpy.

  • Bond Order- According to Lewis, the number of bonds between two atoms in a molecule determines bond order.

FAQs on NEET 2023 Important Questions: Chemical Bonding and Molecular Structure

1. Where can I find important questions of chemical bonding and molecular structure for NEET preparation?

On Vedantu's website, you can find important questions for NEET preparation in physics, chemistry, and biology. You can also practice with sample papers and previous year's question papers. You can get these for free in PDF format. Going over them will offer you an advantage and assist you in better comprehending the topics. You will become acquainted with the paper patterns and will be able to effectively manage your time. Vedantu also has more study materials available for you to download for free. In addition, Vedantu hosts online live sessions with professionals to assist you in resolving your questions.

2. How to prepare for NEET with help of important questions and previous year papers?

Follow these tips to score better in the NEET exam-

  • Make time in your study routine to answer critical questions every day.

  • Know the questions that will almost certainly feature in the tests. Examining examination papers can help you figure this out.

  • Refer to a book with MCQs compiled throughout the years, subject and topic wise, once a chapter has been learned. You've solved problems from prior years while also reviewing the material you've just learned by answering Important questions.

  • Because NEET exams are held in the afternoon session, solve one question paper every day from 2 pm to 5 pm during the last month of the exam. You'll be sure to complete a double revision and analysis this way.

  • The analysis of the papers, as well as important issues, can only be comprehended by keeping track of the number of questions posed.

  • Solve a minimum of ten years' worth of question papers. Because the syllabus of these papers is genuine and up to date.

3. How can I prepare for the NEET exam with the help of important questions?

Follow these tips-

  • Theoretical questions from NCERT must be mastered. 

  • Work through NCERT example questions as well as coaching modules. 

  • Organic chemistry - the method of reactions must be known, which makes it much easier to understand similar reactions. Consistent practice of important questions is essential. 

  • Inorganic chemistry: make a list of key reactions and practice them extensively. This can be found in NCERT. 

  • Physical chemistry - write down all equations as soon as you finish a chapter. 

  • Keep a separate section in your notes for reactions and how they function and separate for important questions. 

  • Take detailed notes and edit them on a regular basis. 

  • Work through old question papers and sample papers and important questions from prior years. 

  • Every day, take a practice test.

4. What is the importance of studying Chemical Bonding and Molecule Structure?

Chemical bonding allows scientists to mix the more than 100 elements of the periodic table in a variety of ways to create chemical compounds and materials. The success rate is quite high, as CAS, a part of the American Chemical Society, presently registers about 120 million chemical compounds.


Grasp Nature's sophisticated design mechanisms and blueprints require an understanding of molecular structure. If we can decipher her designs and basic materials, we might be able to replicate her lovely things at a lower cost and with less negative environmental implications. We can now investigate single molecules thanks to higher resolution instrumentation. Many outstanding contributions to the field have been made in the recent few years. To a few picoNewtons resolutions, we can measure the forces required to unravel particular domains of biological molecules like titin or DNA.

5. Are important questions enough to prepare for the NEET exam?

Most students fail the exam owing to a lack of knowledge, it is critical to be aware of the relevant NEET questions. To easily grasp the question paper, one should study over the entire exam curriculum and make a list of the chapters covered for each subject in the exam. They should review prior year's articles as well as sample papers along with important questions.


The NEET important questions should be studied by every student. Practicing these questions can assist a student in staying ahead of the other competitors. They can also comprehend the proper method to respond to questions. However, because the NEET questions are objective in nature, a student must correctly answer all of them in order to achieve good marks while competing against over a million other students.
