Write the reaction involved. Give chemical test for the following:- a. Benzyl chloride and Chlorobenzene b. Chloroform and Carbontetrachloride |
| Answer» E...here is your answer...a) CHLOROBENZENE (or any aryl halide) is less reactive than Benzyl chloride (or any alkyl halide) because in case of aryl halides, the halogen is directly attached to sp2 hybridised carbon atom.C6H5CH2Cl + aq NaOH --------> C6H5CH2OH + NaCl NaCl + AgNO3 --------> AgCl (white precipitate) + NANO3 Thus Benzyl chloride will give white precipitate with NaOH followed by AgNO3 whereas chlorobenzene will not. b) the reaction of chloroform with chlorine, carbon tetrachloride is manufactured by the reaction of chlorine with carbon disulfide or with methane. The process with methane became dominant, but the process with carbon disulfide remains important where natural gas (the principal source of methane) is not plentiful. Carbon tetrachloride boils at 77° C (171° F) and freezes at -23° C (-9° F); it is much denser than water, in which it is practically insoluble. Formerly used as a dry-cleaning solvent, carbon tetrachloride has been almost entirely DISPLACED from this application by tetrachloroethylene, which is much more stable and less toxic.hope it helps... | |
