Students organic chemistry is easy when you learn by learning function of reagent. Following video provides notes of function of reagents -

Ethers reacts with Atmospheric Oxygen & Give Peroxide . These peroxides are explosive.

In case of organic reaction , mechanism is the key of success . Organic reactions are of three types - (a) Addition Reaction (b) Substitution Reaction (c) Elimination Reactions All the above mentioned reaction involve the use of Electrophile & Nucleophiles. In most of the "electrophilic" reaction we get unexpected Products. Lets understand the formation of Unexpected Products by " Carbocation rearrangement ". Note - Following Video explains all about carbocation rearrangements -

Reduction Means addition of Hydrogen or removal of oxygen . Reducing agent is a substance used to supply hydrogen to other substance . In organic chemistry lots of reducing agents are used , bUt main reducing agents are , Ni/Hydrogen , lithium aluminium hydride etc. Note - Following video will explains basic process of reduction -

Organic chemistry is generally considered as most difficult part of chemistry from exam preparation point of view . But in actual it is the easiest part which a student can prepare . Organic chemistry Involve following components - 1. Nomenclature 2. General Organic chemistry concepts 3. Name reactions & Other reactions 4. Distinguishing tests Following video will help you   for preparation of Organic chemistry   -

Existence of a molecule in more than one structure is called as Resonance. None of contributing structure is actual structure   but actual structure is the hybrid of all the structure. Types of Resonance - (a) Pi-Bond resonance or Mesomeric effect  (b) sigma bond resonance or Hyper conjugation . Condition - (a) Planer Molecule (b) Conjugation ........contd.. Note - Following video will be helpful for Understanding the concept of resonance 

Inductive effect may be defined as the shifting of electron along a carbon chain due to the presence of electron releasing or electron withdrawing group . It is of two types - (a) +I effect (b ) - I effect Inductive effect affects Acidic nature , basic nature etc. Note - Following video will explain Inductive effect in easy way .

Bond line notation means to represent a compound by few lines. Every end and every bent represent one carbon, whose valency is satisfied by hydrogen. Following video will be helpful for explaining the nomenclature.

Ester functional group is R-COO-R . Name should be written as - Name of group Attach to Oxygen   Substituent  + Word root + Primary suffix + Secondary Suffix. Note - Method of naming is give in video ahead.' Poly functional group compounds are those which possess more than one functional group . Out of all the functional group one is selected as Functional group & remaining group as substituent. Note - Method Of naming of such compounds is given in video ahead.

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...
