D Finkelstein reaction

Verified Solution

Answer & Solution

Correct Answer

(A) Williamson's synthesis

Step-by-step Solution

Detailed explanation

This reaction is general methods of preparation from alkyl halides According to this question the reaction which is used for the synthesis of ether is undergoes in SN2 reaction It is formed from the reaction of alkyl halides and sodium ethoxide…

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.

Observe the following data ( \(\Delta_i \mathrm{H}_1, \Delta_i \mathrm{H}_2\) and \(\Delta_{\text {eg }} \mathrm{H}\) represent the first, second ionisation enthalpies and electron gain enthalpy respectively).

Element	\(\begin{gathered}\Delta_i \mathrm{H}_1 \\ \left(\mathrm{~kJ}\mathrm{~mol}^{-1}\right)\end{gathered}\)	\(\begin{gathered}\Delta_i \mathrm{H}_2 \\ \left(\mathrm{~kJ}\mathrm{~mol}^{-1}\right)\end{gathered}\)	\(\begin{gathered}\Delta_{\text{eg}}\mathrm{H}\\ \left(\mathrm{kJ}\mathrm{mol}^{-1}\right)\end{gathered}\)
I	\(520\)	\(7300\)	\(-60\)
II	\(490\)	\(3051\)	\(-48\)
III	\(1681\)	\(3374\)	\(-328\)
IV	\(2372\)	\(5251\)	\(+48\)

Using the data identify the most reactive metal.
