B. In Kolbe’s reaction, 2-hydroxy benzoic acid (salicylic acid) is prepared by the reaction of phenol with gas.
C. When a 2° alcohol is allowed to pass overheated copper at 573 K, dehydrogenation takes place and a ketone is formed.
D. Williamson synthesis is an important method for the preparation of ethers. In this method, an alkyl halide is allowed to react with sodium alkoxide.
