Unimolecular: the main difference reactions mixed up with substitution (SN1 and SN2) ... Tip: Recall that the rate of a reaction depends on the.
Refluxing the reaction with CaCl2: Would this make a difference? focuses on nucleophilic substitution reactions either SN1 or SN2.
SN1 stands for Substitution Nucelophilic Unimolecular and SN2 stands for Substitution Nucleophilic. Bimolecular. Both are simple nucleophilic substitutions
mol•sec. Nucleophilic Substitution comes in two reaction types: SN2. SN1 The order of reactivity of the alkyl halide in the SN1 reaction.
