6. What happens when (i) Propanoic anhydride reacts with \( \mathrm{PCl} 5 \) and resulting product is treated with 2-propanol (ii) The product of nitration of benzene is completely reduced with \( \mathrm{Zn} / \mathrm{HCl} \) to an amine which is further treated with ethanoylchloride. (iii) 2-Aminopropane reacts with ethylbromide and resulting product is boiled with \( \mathrm{NaNO} 2 \) and \( \mathrm{HCl} \). (b) How acetaldehyde can be distinguished from other aldehydes and ketone? Write the test with a chemical reaction.
