Chapter 12 of the textbook talks about organic chemistry. Organic chemistry is a specific branch of chemistry. It is extremely important especially for those students who wish to study the subject in higher classes as well. A conceptually strong grip over the fundamentals of the topic definitely comes in handy in the future when appearing for different competitive exams and seeking admission in colleges/universities. This branch of the subject details at length, the structure, compositions, properties, and reactions of compounds containing carbon.
