ANSWER

An organic aromatic compound 'A' with the molecular formula C6H7N is sparingly soluble in water. 'A' on treatment with dilute HCL gives a water soluble compound 'B'. 'A' also reacts with chloroform in presence of alcoholic love to form an obnoxious smelling compound 'C'. 'A' reacts with benzene sulphonyl chloride to form an alkali soluble compound 'D'. 'A' reacts with NaNO2 and HCl to form a compound 'E' which on reaction with phenol forms an orange red dye 'F'. Elucidate the structures of the organic compounds from 'A' to 'F'.

Brownian motion or pedesis (from Ancient Greek: "leaping") is the random motion of particles suspended in a fluid (a liquid or a gas) resulting from their collision with the fast-moving molecules in the fluid.
