Remember some of the main lessons from the previous chapter: Higher Nucleophilic aromatic substitution is a classical reaction in which a nucleophile displaces a leaving group on an aromatic ring. 2. In the substitution reaction, we have an electron-rich species (the oxygen) donating a pair of electrons to an electron poor species (the carbon) Reduction reactions often proceed via nucleophilic attack mechanisms, especially when hydride donors are involved. It is generally seen in the reactions of tertiary or secondary alkyl halides with secondary or tertiary alcohols under strongly acidic or strongly basic conditions. Now, finally, let's take a look Learn about nucleophilic substitution in this engaging video lesson.
