Course Synopsis

the course contains concept of Acids and bases, importance and role of Pka values in an reaction. nucleophilic substitution is also part of this syllabus, mechanism of substitution reaction and stereochemistry is also discussed. Substitution reaction in aromatic reaction also play a very important role in synthetic chemistry. Elimination reactions , factor effection on elimination reactions and mechanism of Elimination reactions is also including in this course.
