Which of the following cannot be made by using Williamsons synthesis?a...
Explanation:
Williamson's synthesis is a commonly used method for the preparation of ethers. In this method, an alkoxide ion (RO-) is reacted with an alkyl halide or an aryl halide to form an ether. However, there are certain limitations to this method. One of the limitations is the steric hindrance caused by bulky groups.
Di-tert-butyl ether is a bulky ether and cannot be prepared by Williamson's synthesis. This is because the tert-butyl group is too bulky to allow the formation of the intermediate alkoxide ion, which is necessary for the reaction to occur.
On the other hand, methoxybenzene (anisole), benzyl p-nitrophenyl ether, and methyl tert-butyl ether can be prepared by Williamson's synthesis since they do not have bulky groups.
Therefore, the correct answer is option D, di-tert-butyl ether.
