luction Nucleophilic substitution is a tremendously useful and important reaction in organic chemistry. No s it used extensively in organic synthesis, but some biochemical processes also proceed via nucleophili Litution mechanisms. Often, nucleophilic substitution is one of the first organic reactions covered and it efore very important to understand it thoroughly. This experiment investigates the relative nucleophilicity of chloride and bromide ions. Also of interes ow varying the degree of substitution at the electrophilic center affects the reaction mechanism. The...
