WebCorrect option is D) 2-iodo-2-methylpropane is a tertiary alkyl halide. This will undergo dehydrohalogenation on reaction with strong base such as sodium ethoxide to form 2-methyl-prop-1-ene which is an alkene and not an ether. Williamson's reaction follows SN 2 mechanism. Thus, Williamson ether synthesis will fail in this case.

The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol (alkoxide). This reaction was developed by Alexander Williamson in 1850. Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an SN2 reaction. This reaction is important in the history of organic chemistry because it helped prove the struc… WebIn Williamson synthesis, an alkyl halide reacts with an alkoxide ion. Also, it is an S N 2 reaction. In the reaction, alkyl halides should be primary having the least steric hindrance. Hence, an alkyl halide is obtained from ethanol and alkoxide ion from 3-methylpentan-2-ol.
