Reaction mechanism involve a series of steps which represent a chemical Reaction. A species which is formed during a reaction & gets consumed during the reaction is called as Reaction Intermediate . Lets understand The Role of "Benzyne" Intermediate in the "reaction mechanism " of "Organic Chemistry" by Following video -

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 -

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...

Alcohols are the Mono alkyl derivative of water. Phenols are Phenyl derivative of water.

The key of Sure success is the regular mock tests. Mock test means to perform in the real - like environment . PICS INSTITUTE organise free mock test of All India students as well out side students through AITS i.e. All India Test series. Any Student of Class XI & XII can participate in this test. Note - More Information is in following video - 

Here I am providing most effective method for preparation of chemistry for class XII | XI | NEET | JEE . Chemistry is one of the most important subject for getting Good rank in NEET & JEE , But it require a planned approach for success . Following video explains all about preparation of chapters - Solutions , Solid state & Electrochemistry for Class XII.

Organic chemistry class XII  Haloalkanes or Alkyl halides are the Halogen derivatives of Alkanes. Haloarenes or Aryl halides are the Halogen derivative of Benzene. Classification of Haloalkanes - They are of following types -  (a) Primary (b) Secondary (c) Tertiary halide.. Note - Following video explains the full Haloalkane & Haloarenes in details -  Note -  NOTES CAN BE DOWNLOADED BY CLICKING HERE.     Books for NEET | JEE | XII | XI - Objective chemistry for NEET - http://amzn.to/2wdPr3K Objective chemistry for JEE9Mains + Advance) - http://amzn.to/2xJ2nwl Organic chemistry objective Book - http://amzn.to/2vFMPIl Inorganic chemistry Objective Book - http://amzn.to/2xIAxR2 Physical Chemistry Objective - http://amzn.to/2wezXwA Objective Errorless Chemistry for NEET | JEE - http://amzn.to/2wefQOI Objective by R.C.

NOTE -  CLICK HERE FOR DOWNLOADING THE PDF OF QUESTIONS & ANSWERS 1.) Why do haloalkenes under go nucleophillic substitution whereas haloarenes under go electophillic substitution . Ans. Due to more electro negative nature of halide atom in haloalkanes carbon atom becomes slightly positive and is easily attacked by nucleophillic reagents. While in haloarenes due to resonance, carbon atom becomes slightly negative and attacked by electrophillic reagents. reagents. 2.) When an alkyl halide is treated with ethanolic solution of KCN, the major product is alkyl cyanide where as if alkyl halide is treated with AgCN,the major product is alkyl isocyanide. Ans. KCN is ionic they can attach through C or N but C-C bond is strong than C-N bond. So alkyl cyanide is the major product but AgCN is covalent so more electronegative N can attach to C and forms isocyanides. 3.) How do primary , secondary & tertiary alcohols differ in terms of dehydrogenation? Ans. 4.) Why ar...

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 -

Lots of career options are available for today is student. But still students always remain confused about their future. Many students opt for prestigious examination like engineering and other of MBBS medical.
