How can you easily differentiate between these reactions?

A positive charge-seeking reactant will be used in electrophilic substitution to replace a group on your organic compound.

b. Electrophilic addition: this process combines your organic compound with a reactant that seeks positive charge.

c. Nucleophilic substitution: This process entails substituting a functional group on your organic compound with a reactant that seeks negative charge.

d. Nucleophilic addition: this process combines your organic compound with a reactant that seeks out negative charge.

To easily differentiate between reactions, you can look at factors such as the reactants involved, the products formed, the conditions under which the reaction occurs (such as temperature and pressure), and any observable changes in properties (such as color change or gas evolution). Additionally, reaction mechanisms and kinetics can provide insights into how reactions occur and what distinguishes them from one another.
