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

What are mantra ? A simple question but a wide meaning . "Collection of few words , which helps in gaining desired results" Every ritual in every religion has lots of such mantra's. Mantras are simply few affirmations which we repeat regularly & transfer that in the deep memory of our self. What we think what we are. These words modify our behaviour according to the our desire . If you are a student , Chant your aim religiously  , regularly , you will see change in your attitude. Note - Following video will help you in understanding the "Power of MANTRA "

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...

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 .

Every Organic reaction possess - 1.Reactant 2.Reagent 3.Solvent 5.Product 6. Leaving Group Nucleophile is the species which attacks on positive charge or electron deficient center. Electrophile is the species which attacks on Negative charge or electron rich center. Ambiphile is the species which act as both Electrophile as well as Nucleophile. Note - Following video Explains entire concept effectively

Aromatic compounds are those which possess - 1. Cyclic structure 2.Planer structure 3.Conjugation 4. Huckle rule Anti-Aromatic compounds are those which possess - 1. Cyclic structure 2.Planer structure 3.Conjugation 4.  4n pi electron Note - Following video will explain entire concept -

DownLoad the notes from link 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 .

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. PICS INSTITUTE is constantly doing efforts for the uplifting the student's confidence in chemistry . We have started Free Course in Organic chemistry on our YouTube channel "pics4iit". We are providing free worksheets & support for subscribers & registered students. Here we are posting the answers of the 1st - Exercise of "IUPAC Nomenclature"
