Chemistry Spl

Hey,
Follow these books if you are appearing for it next year. If this year, then there is less time. So, you go through NCERT:
*Physical Chemistry by O.P. Tandon
This book covers the entire Physical Chemistry syllabus including Atomic Structure, Radioactivity and Nuclear Transformation and Stoichiometry. It has theoretical and numerical problems, which make it a must-have for all those who are preparing for JEE Advanced examinations. Topics like Energetics, Chemical Kinetics, Chemical Equilibrium, Solutions and Electrochemistry are very well explained.
*Organic Chemistry by Paula Bruice Yurkanis
A perfect blend of concept clarity and its application, the part 1 and part 2 in the Paula Bruice Yurkanis book have been presented exceptionally well. Part 2 deals with Hydrocarbons, Steceo Chemistry, and Resonance. Part 3 deals with Substitution and Elimination Reactions.
*Chemistry XI & XII by NCERT
Topics best covered in NCERT Inorganic Chemistry syllabus are Preparation and Properties of Non-metal, Transition Elements, Ores and Minerals, Extractive Metallurgy and Group Analysis. The books clearly define concepts and theories along with a lot of exercises and practical activities to reinforce them.
All the best.

There are four core branches of engineering i.e mechanical, chemical, civil and electrical. Each of these branches has developed into many specialised sub-branches. The number of engineering degrees available has increased dramatically in last few years. For example, electrical engineering is further divided in specialisations such as electronics, instrumentation, telecommunication, computer science, information technology, etc. Mechanical engineering also has specialisations such production, aeronautical, etc. Chemical engineering is further divided in petrochemical, polymer technology, etc.
Trends in various engineering branches scope and opportunities vary with multiple parameters such as economic growth, geopolitics, innovation and technology changes, shortage of skills, quality of education, changes social capital, etc. Therefore, predicting branch wise trends is very difficult. Currently, the scope for B.Tech in CSE and ECE graduates is the highest. Mechanical engineering is an evergreen branch of engineering with not much change in scope in last 5 decades.
You must choose the branch of engineering based on your interest to excel.
