Introduction
Chemistry is the branch of science which not only deals with the matter but also with interaction among various particles of matter and their transformation to form new particles. It shares the concepts with physics to study the inter conversion of matter and energy. Chemistry makes foundation for the study of bio-molecules and biological systems under the topic biochemistry. Chemistry can mainly be divided into three branches:
1. Organic chemistry: This branch of chemistry deals with the study of carbon and its compounds.
2. Inorganic chemistry: Inorganic chemistry deals with the study of elements of periodic table and their properties and important compounds.
3. Physical chemistry: As mentioned, this branch shares its concepts with physics to deal with the energy and matter transformation.
Importance of Chemistry
Chemistry has a wide range of applications in our day to day life. From medicines to cooking oil, from engine oil to hair oil- these are all chemicals. Everything which we see around us is actually a chemical. Even our body is made up of chemicals and our biological processes work on the principles of chemistry.
The environmental studies are also based on concepts of chemistry. Techniques of salt analysis are used to find out contamination of water bodies and air to find out the pollution level and prevent its harmful effects. Chemistry also finds its application in industries, manufacturing, metallurgy, rubber industry, textile, food industries etc.
Chemistry for Exams:
Chemistry is always a scoring subject for both board exams as well as JEE and NEET if the concepts are clear. Just like any other subject, chemistry is also based on certain fundamental concepts that we need to master in order to score well. For competitive exams also the questions of chemistry (inorganic chemistry specially) are directly based on concepts and facts which one can answer in a few seconds without any error. Organic and physical chemistry are more complex and need extra practice.
· Inorganic chemistry: Questions are directly based on facts or on direct application of the concepts. You must be clear about the periodic table and the periodicity in properties along with the electronic configuration of elements.
· Organic chemistry: Slightly more complex and is the most important segment of chemistry. Questions may be simple or complex. One needs to master the inductive, resonance and electrometric effect to learn and score well in organic chemistry.
· Physical Chemistry: Shares the concepts of physics and mathematics. Most of the questions are based on mathematical formulas and one needs to excel with calculations and mathematical approach to score well in physical chemistry.
Career in Chemistry
· B.Tech and MBBS: If you want to become a doctor or an engineer, you will have to clear entrance exams like NEET and JEE. Chemistry being a scoring subject, helps you to get good rank so that you become eligible for the admission in top institutions.
· B.Sc. and M.Sc: You can also take admission in B.Sc. followed by M.Sc in chemistry if you want to get in depth knowledge of the subject. This makes you eligible for career in food industries, pharmaceuticals, and chemical industries.
· Research: After doing B.tech or M.sc you can go for research for which you need to clear NET.
· Teaching Profession: Just like any other profession, teaching is also an option for chemistry provided you have passion and the ability to connect with people and you can contribute in the making of career of many more students like you.
