CHEMISTRY CLASSES BY PRADEEP SHARMA

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

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.

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

Fear of organic can be easily rid of if you prepare it systematically. Let's understand the most powerful method to prepare organic for board as well as competitive examinations. Organic chemistry demands repeated written revision. Always revise new organic concept at least 2 times by writing. Page -1 :- On page number 1 just write down mechanism of organic reaction like SN1 , SN2 , SN-Ar & SN-th. Write all the factors of this mechanism along with sample problem on the first page. Page-2 :- On the page number 2 write the topic of general organic chemistry. Inductive effect, resonance effect ,Carbocation, hyperconjugation must be present on this page. Write all the sample problems on this page for these concepts. Page-3 , 4 :- On this page write the function of all the reagents in respective chapters along with the example of that reagent. If you need two pages then use two pages and solve the questions on these two pages. Page-5 :- On this page wri...

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 !!!

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

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.

Higher aims require smarter way of preparations .. Following video explains the smartest way of preparation of NEET & JEE -

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 -

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   -

Reaction intermediates are those species which are produced during a reaction & get consumed during a reaction . These are of following types - (a) Carbocation (b) Carbanion (c) Free radical (d) Carbene (e) Nitrene (f) Benzyne Note - Following video will explain Carbocation & Carbanion .

Nomenclature means to assign name to any substance . In organic chemistry names are of two types - (a) Common names (b) IUPAC names. Common names are also known as Trivial name. Following Notes will help you in understanding IUPAC as well as common nomenclature. Note - Videos are given in last. NOTE -  CLICK HERE FOR DOWNLOADING THE BOOK ON NOMENCLATURE OF ORGANIC COMPOUNDS  

DownLoad the notes from link given in last . Haloalkanes - Alkyl group + Halogen Haloarenes - Arkyl group + Halogen Ø Chain isomerism:        CH 3 CH 2 CH 2 CH 2 Cl            1-chlorobutane,        CH 3 CH - CH 2 Cl           1-chloro-2-methylpropane                |               CH 3 ● Ø Position isomerism: Ø CH 3 CH 2 CH 2 Cl    1-chloropropane Ø CH 3 CH 2 ( Cl ) CH 3 2-chloropropane Ø Optical isomerism:         Alkyl halides      :               C 3 H 7 X           C 4 H 9 X   ...

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 .

Dear Students , Try to solve the Questions given in the video based upon Nomenclature . This exercise is highly useful for NEET | JEE | XII | XI - https://www.youtube.com/edit?o=U&video_id=ODqM6_8Hu6o
