Q.Chloroform reacts with Nitric acid to produce:

Chloroform (CHCl3), the classic trihaloalkane, is made in the lab by the haloform reaction from ethanol and bleaching powder (a combined source of Cl2 and Ca(OH)2), in three distinct steps: (1) OXIDATION of ethanol to acetaldehyde by Cl2; (2) CHLORINATION of acetaldehyde (three successive Cl2 substitutions) to trichloroacetaldehyde, chloral; (3) HYDROLYSIS of chloral by Ca(OH)2 to give chloroform + calcium formate -- so the very name 'chloroform' comes from this hydrolysis step yielding formic acid/formate. Chloroform is a colourless, sweetish-smelling, burning-tasting liquid whose vapour depresses the central nervous system (hence its historical use as an anaesthetic) -- a use abandoned once its slow aerial OXIDATION in light to the highly poisonous gas phosgene (COCl2) was recognised, which is exactly why chloroform is stored with a little ethanol (which scavenges any phosgene formed) in a dark bottle (which blocks the light that drives th …
