I am a XI Class student from Telangana, a 10 CGPA achiever in 10th Board Exam and a JEE Advanced 2017 aspirer. I am doing well in Mathematics and Physics but Chemistry holds me back. I am looking for a good Referrence book which is Concept building and also good practice questions. But I am confused what book to choose. I hear names like O.P. Tandon, but I do not want to be a sheep in the herd. I am looking for THE BEST. Some of my Options are:

• Organic Chemistry by Morrison and Boyd and S.B.Bhattacharjee
• Organic Chemistry for JEE Edition by Morrison, Boyd and S.B. Bhattacharjee
• Organic Chemistry by O.P. Tandon and A.S. Singh.

Please suggest any one of the above books or something else if it is good. Thank you.

Two lines are inclined at angle 'a' each parallel to each other. A ball is projected from the midpoint of both lines at an angle 'b' with the direction of the lines. The ball just touches one line and hits the other line perpendicularly. Prove that tan b = (√2 - 1) tan a

Is 75pecent criteria required overall 

If a person don't have 75 in pcm aggregate and individually too in pcm

But have pcmEngPhyed /500 aggregate overall to be 75 

Will he be eligible for iits nits?

For the gas phase reaction SO3(g) SO2 (g) + ½ O2 (g) if the gaseous mixture in a closed container is allowed to come at equilibrium and the degree of dissociation (α) at equilibrium is found to be 2/3 at 400 K and 1 atm pressure then calculate the vapour density of the equilibrium mixture.
