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 are th

In today's world it is a very big problem " How to maintain good relations between parents & child" A child always complains about his/her freedom , desires etc. Parents have their different issues with kids.  Following video will be help full in dealing with such problems - 

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. But still lots of student remain without any choice.  Here I am suggesting few of the evergreen career options for a student. These are - 1. PHYSIOTHERAPY  2. Hospitality management  3. Merchant navy  Note - Following video will be helpful for understanding Top 3 evergreen career after class XII -

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   -

Lots of students always face a situation of confusion  while preparing for their future i.e. NEET & JEE. They always think ..is it possible to clear NEET & JEE ? Lakhs of students every year under go coaching for appearing in these prestigious exams but only few can realize their dreams . Following video will help in low coast preparation of competitive exams.

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 .

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 

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.

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 .

For the various competitive and board examinations, to identify the structure from name is very important for organic chemistry.Organic conversions can't be solved without knowing the structure. Here are the some effective methods foe writing structures from the name. Steps are as follows : 1. Write the number of carbon atom according to word root. 2. Give number to each Carbon. 3. Place word root , multiple bond and functional group according to their position as represented by      name. Note : Following video explains the method in detail for writing the structure from name..
