Reasoning Questions of Organic Chemistry

Lots of questions in organic chemistry comes from the reasoning section. Each and every chapter of organic chemistry possess large number of reasoning questions. Answer of most of the question is based on resonance and inductive effect. A student must have prior knowledge of resonance and inductive effect to solve all the problems correctly. In case of halo alkanes and halo airings most of the questions comes from reactivity. Answers of all these questions are based upon resonating structure and partial double bond. In case of alcohols and phenols most of the questions are from acidic strength. Again strong knowledge of resonance and resonating structure can help in solving such type of questions. In case of aldehydes and ketones most of the questions are based on reactivity and the answer of these questions are based upon inductive effect. In case of a Amines maximum questions appears from basic strength and the answer in wall both residents as well as inductive effect...

How to prepare for chemistry exam - Step wise preparations.

Students this is exam time , don't get panic , be prepared for a glorious performance towards brightest future .  This is the time which required a programmed approach for learning . Here I am providing stepwise method for learning chemistry for examination . First of all make your schedule in exam friendly manner and not student friendly manner . Your schedule should involve 2.5 hours at least for each subject . This 2.5 hr must be divided in two steps 2 hrs for fresh learning and 0.5 hr for revision . For chemistry learn those chapters which are easy first .  CHAPTER wise Pattern Class XII students can revise in following pattern -  1. Polymers 2. Chemistry in every day life  3. D and F block elements  4. Coordination compounds . 5.solid state  6. Solutions  7. Electro chemistry 8. Chemical kinetics  9. Halo alkane and Halo arenens 10. Alcohol , phenol and ether 11. Carboxylic acid  12. Amines , diaz...
