The mechanism for the given reaction should be determined. Concept Introduction: Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via E1 (the reaction depends only on the substrate involved in the reaction) or E2 (the reaction depends on both of the substituents in the reaction) mechanism. Substitution Reaction: It is type of reaction where one group present in chemical compound gets substituted by another functional group . Acylation: It involves addition of acyl group R- C || O -/ to compound. Nucleophile: donates pair of electrons to positively charged substrate resulting in the formation of chemical bond . Leaving group: it is a fragment that leaves the chemical compound with pair of electrons in a heterolytic bond cleavage. Carbocation: it is carbon ion that bears a positive charge on it. Proton-Transfer: It is a type of chemical reaction in which the protons gets transferred from the acid to the base. It is used to remove the positive charge present in the substrate due to neutral nucleophile in substitution reaction. Aromatic Compounds : Compounds that are planar, cyclic and having ( 4 n + 2 ) π electrons are known as aromatic compounds. Non-aromatic compound are either not cyclic or not planar.
