hello aspirant,

It is really difficult to get a good score in chemistry with out any coaching. and for organic chemistry part you need lot of practice. as per your questions its clear that you did not studying any thing. so I would suggest you to read physical and inorganic chemistry. physical chemistry is easier than organic and inorganic you need to have good memory. thus you may get 30-40 marks. try to get help from any good teacher who can give some suggestion to you.

Dear Vijay, you haven't mentioned if this is for JEE Mains or NEET. So we shall help you with JEE preparation tips. Do let us know if this is for another entrance examination please. Chemical Bonding and Molecular Structure, Bio-molecules, Polymer, Aldehyde Ketone and Carboxylic acids, Equilibrium, Coordinate Compounds etc. constitute the major part of the Chemistry paper. It is further added that Qualitative Analysis, General principles and Processes of Isolation of Elements and Surface Chemistry etc. have lesser number of questions in the exam. If you can memorise the periodic table, chemical formula of each gas and their structure, Chemistry can be easier for you. Focus on focus on Organic Compounds containing Oxygen, Equilibrium, Basic Concepts, and Chemical Bonding and Molecular Structure.
