The preparation of dialkyl zinc from zinc and alkyl iodide is called the Frankland reaction.
In Wurtz's reaction, two alkyl halides are reacted with sodium metal in dry ether solution to form a higher alkane.
An alkyl halide is allowed to react with sodium alkoxide to form symmetrical and unsymmetrical ether and the reaction is called Williamson's synthesis. Hence, diethyl ether can be prepared using Williamson's synthesis.

it was found that $\mathrm{E}_{\mathrm{a}}$ is decreased by $30 \;\mathrm{kJ} / \mathrm{mol}$ in the presence of catalyst.
If the rate remains unchanged, the activation energy for catalysed reaction is (Assume pre exponential factor is same $):$
