Nucleophilic substitution reactions are especially prominent in organic chemistry due to the propensity of nucleophiles to attack carbon atoms, which can bind up to four other atoms and participate in double and triple bonds. A nucleophilic substitution reaction will occur if the attacking nucleophile is...
