A Rapid and Innovative Method for the Identification of Aromatic and Anti-Aromatic Nature of Organic Compounds.

Abstract: Prediction of aromatic and anti-aromatic behavior of organic compounds is a vitally important tool for students of chemistry at graduate and post-graduate level for solving different kinds of problems regarding reactivity, stability and acidic properties etc. In this manuscript we try to present a simple and innovative method for easy identification of aromatic and anti-aromatic behavior of organic compounds from their non-aromatic nature excluding Huckel’s rule of aromaticity.

Simple Thinking Makes Chemistry Metabolic and Interesting - A Review Article

Abstract: First of all I give my love to all the students who reside in 'Chemistry Phobia zone'. In this short article I shall try to share my simple thinking that I achieved during my last 16 years of journey in the route of Chemical Education. Before starting my journey it was a big encounter for me to change the conventional methods and makes chemistry easier and interesting to such student who belongs to Chemistry Paranoia Zone. I believe that students are just like flowers and it is our duty to nourish them properly as a gardener. In my infinitely small area of knowledge, I just try to innovate fourteen (14) teaching methodologies by including thirty four (34) completely new formulae in the chemistry world which were followed by different eminent writers in their books since last 90-95 years namely Sir G.Wilkinson, Prof. F. Albert Cotton, Prof. I.L.Finar, Prof. R.T. Morrison, Prof. R.N. Boyd, Prof. Solomons and Prof. Fryhle, Prof. J.G. Smith etc.. homo and hetero nuclear molecules or ions having total electrons (01-20) using M.O.T., bond-order of oxide based acid radicals, 'IUPAC nomenclature of spiro and bicyclo compounds, 'spin multiplicity value calculation', 'Aromatic and Anti-Aromatic behavior of Organic compunds', 'magnetic properties of homo and hetero nuclear diatomic molecules and ions, 'simultaneous equations as a tool in the spectrophotometric analysis of two non-interacting substances in a binary mixture, prediction of Magnetic Moment of homo and hetero nuclear mono and diatomic molecules or ions without MOT, calculation of the number of π-bonds, σ-bonds, single and double bonds in aliphatic unsaturated open chain and cyclic olefinic hydrocarbons and alkyne system etc. is time consuming. Keeping this in mind, I introduced some new innovative methods 12-23 to make chemistry

New methods for the prediction of magnetic moment of homo and hetero nuclear mono and diatomic molecules or ions without mot-a rapid innovative approach

Abstract: Prediction of magnetic moment without M.O.T. is of vital important tool to students of applied chemistry for solving different kinds of problems related to magnetic behavior. In this manuscript I try to present a simplest time saving innovative method for the identification of magnetic behavior of homo and hetero nuclear mono and diatomic molecules or ions having total electrons (01-20) excluding MOT concept. This method is not applicable for polyatomic molecules such as BCl3, CCl4, SO2 etc.

Simultaneous Equations as a Tool in the Spectrophotometric Analysis of Two Non - interacting Substances in a Binary Mixture: Senior Undergraduate Physical and Physical-Organic Chemistry Laboratory Experiment

Abstract: A simple and lucid spectrophotometric way of analyzing a mixture of two compounds is explained in this article for senior undergraduate level students. The essential feature of this method is that there should be at least 30-40 nm difference in the λmax of the two compounds so that there will not be any overlap of the two individual spectra of the two compounds when recorded together in a mixture.
