Which of the following statement is incorrect with Williamson synthesis?
Answer: D
The incorrect statement is Secondary or tertiary alkyl halides gives better results of ether formation.
Williamson synthesis is an SN2 reaction, which works best with primary alkyl halides. Alkoxides are strong bases as well as nucleophiles, so with secondary and especially tertiary halides elimination wins and alkenes form instead of ethers.
The other statements are true: the method makes both symmetrical and unsymmetrical ethers from an alkyl halide and a sodium alkoxide, by SN2 attack, and alkoxides are both nucleophiles and strong bases.
