Fore Note to UPSC Chemistry Syllabus
Note First and foremost, you must talk to someone who has taken Chemistry as an optional earlier and take their advice. There has been a common misconception among the students that UPSC Chemistry Syllabus is a hard nut to crack and its better to leave it as an optional paper. You are absolutely wrong.
Even through the Chemistry Syllabus portion in UPSC looks very huge and hard to study, once you start reading through few chapters, you will come to an absolute conclusion that UPSC Chemistry Syllabus is one of the most interesting and easiest of all the papers in entire UPSC Syllabus.

Conclusion on UPSC Mains Chemistry Syllabus
It is always said that the wise men words are often neglected. However, we would like to again stress the fact that the Chemistry Syllabus in UPSC is one of the most important and crucial things that has to be properly taken care of.
Not just for examination point of view, Chemistry Syllabus in UPSC helps you in the overal development to become a good responsible officer who will play a crucial role in the development of the country in the decades to come.
Chemistry can be a good optional if you are extremely brilliant at it but i do have a few problems. Chemistryis not going to help an ias in any possible way.
There has been a news circulating that, UPSC may remove optionals in coming years.mind you its not a rumor but actual happening in near future.
