Evaluate your "basic concept of chemistry"

   A sample containing Cu₂S, Cu₂O and 50 millimole of an inert gas is treated with 500 meq. Of acidic KMnO₄. The entire Cu is converted to Cu⁺² and the resulting solution is diluted to 50 ml. A 5 ml. of diluted solution is treated with excess of KI solution, Iodine is liberated and it is filtered. Now it is diluted to 50 ml. 5 ml of this liberated iodine requires 10 ml of 0.2 N Na₂S₂O₃. Find out the mole fraction of Cu₂S and Cu₂O in the given sample. 

physical chemistry for iit jee

Physical Chemistry requires a good understanding of concepts. Try to understand all the formulae used in physical chemistry, instead of just applying them blindly, as a particular formula may not be applicable to the question. (Example, instead of a dilute solution, the given solution may be concentrated, making most formulae invalid, in that case understanding of the basic principles will help.) Try to solve various types of problems for perfection in physical chemistry,.physical chemistry is like mathematics it required lot of practice.

How to Study Organic Chemistry for IIT JEE?

Although Organic Chemistry in itself is quite vast but at IIT JEE level it deals with General Organic Chemistry i.e. basics organic chemistry.It starts with the concept of Hybridization, IUPAC Nomenclature, Isomerism, Resonance, Hyperconjugation, etc. Stereoisomerism is a critical part which becomes a bottleneck for most of the students. These concepts are used in almost every reaction mechanisms which are a part of topics like Hydrocarbons, Halides, Alcohols & Phenols, Aldehydes & Ketones, Carboxylic acids and derivatives and hence these are basics of organic chemistry. Named Reactions are like drivers direction for students and maximum come from the chapter of Aldehydes & Ketones, which is no less than a climax of a movie.
