Reactant which undergoes elimination reaction more rapidly has to be identified. 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 base and substituents in the reaction) mechanism. Elimination reaction of an alkyl halide results in the formation of an alkene . Relative relativities of alkyl halide in an E2 reaction are 3°> 2°> 1° . Also E1 reaction takes place only on tertiary alkyl halides . Leaving group: It is a fragment that leaves the chemical compound with pair of electrons in a heterolytic bond cleavage. Down the group, atom size decreases which in turn reduces the tendency of atom for donating electrons and hence basicity decreases making them a better leaving group.
