💡 Solution & Explanation

Correct option: \(\text{C}\). Alkyl halides undergo nucleophilic substitution by \(\mathrm{S_N1}\) or \(\mathrm{S_N2}\). \(\mathrm{S_N2}\) gives backside attack and inversion, while \(\mathrm{S_N1}\) proceeds through a carbocation and can racemise. Recovered question text: 22. The reaction of ethyl iodide with sodium ethoxide is (1) An electrophilic substitution reaction (2) A nucleophilic addition reaction (3) A nucleophilic substitution reaction (4) A free radical substitution reaction
