Electron Displacement in Organic Molecules

About this course

This course begins with a discussion on different types of effects which are responsible for electron displacement in a molecule –· Inductive effect· Mesomeric effect· Electromeric effect· Each of these are explained in detail with suitable examples.· The examples of +I and -I, +M and -M and +E and -E groups are included exclusively, in connection with various effects.· The impact of these effects on various behavioural properties of molecules are highlighted with prominent examples.The next section of the course is structured on acids and bases of organic nature.· The general acid-base concepts – Arrhenius, Bronsted - Lowry and Lewis Concept are explained with examples.· The quantitative and qualitative expression which includes the strength of an acid and base are explained in the beginning.· Later, the course primarily focuses on organic acids and bases, their properties and behaviour.· This course includes a section highlighting the factors encompassing the stability of a conjugate base.· The periodic trends governing acid strength is explained with significant examples.· This course also provides a simple and easily memorizable acidity order based on the pka values.· The chemical concepts governing this acidity order are also explained with examples.· The course is supported by practice problems and NOTES (downloadable) at the end of each section.

Course objectives

• to explain electron displacement effects using examples
