Course Synopsis

this course include mainly addition reaction on carbon carbon double bond and carbonyl compound, what is the role of electrophile and nucleophile in such type of addition reactions and what type of compound can be made through addition reaction and how acid and base catalysed the reactions. Elimination reactions is also a part of this course.

Course Learning Outcomes

To understand the addition reaction and learn about the how addition take place in carbob carbon double bond and carbonyl compounds. To learn the mechanism, importance of Elimination reaction and factor effects on it.
