16. (a) Suggest appropriate reagent(s) for the following transformations: (i) \( \text{MeO}_{2} \text{C} \) \( \begin{array}{c} \text{O} \\ \text{C} \end{array} \) \( \text{CO}_{2} \text{H} \) \( \longrightarrow \) \( \text{HO} \) \( \begin{array}{c} \text{O} \\ \text{C} \end{array} \) \( \text{CO}_{2} \text{H} \) (ii) \( \text{MeO}_{2} \text{C} \) \( \begin{array}{c} \text{O} \\ \text{C} \end{array} \) \( \text{CO}_{2} \text{H} \) \( \longrightarrow \) \( \text{MeO}_{2} \text{C} \) \( \begin{array}{c} \text{O} \\ \text{C} \end{array} \) \( \text{OH} \) Which type of selective reaction is typified by the above transformations? (b) Complete the following reaction using plausible reaction mechanism to justify your answer. \( \text{NaOH} \)
