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

Limiting reactant means the substance which gets completely consumed during the chemical reaction . Excess reactant means the substance which remains during the chemical reaction. Following video will help you understanding the limiting reactant.

Dear students you can download the notes of coordination compounds from the description of following video .

Organic conversion is the most interesting part of organic chemistry  . It can be easily by watching our following video series -

Organic reagents means the substance used for a particular chemical reaction. If you know  the  function of  Regent you can easily remember and Complete a chemical reaction. students let's understand the easiest way of learning organic chemistry. Following video explain most easiest method to understand organic chemistry.

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 -

Do have complaint about Luck & Success ? Lets first of all answer followings - 1. Are we actually programmed by luck ? 2. Is their any thing left to do in our life ? 3. So why we complain others for our failure , if everything is predetermined? 4. Is our life not going to change ? अगर ये सब प्रश्न के जवाब आप हाँ मैं देते हैं। … तो आप को आकस्मिक सहायता की जरुरत है !!!!!!!!!!! We don't know about luck , whether it exists or not !!! But what we can do , is to make our self more powerful in our thoughts and behaviour . "ऐ वक़्त ज़रा अदब से पेश आ , वक़्त नहीं लगता वक़्त बदल जाने में " Friends today I am disclosing the secret of being more powerful and key person in your organisation and in your life - दोस्तों आज कुछ बातें बताता हूँ आप को powerful बनाने के लिये - "PRADEEP's POSTULATES LAW OF BEING POWERFUL" 1. Your Action Creates a CHAIN reaction - Never respond immediately on any unfavourable situation . Take time to analyse situation & then...

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..
