Question

When glycerol reacts with nitric acid, in presence of conc. $H_{2}S{O}_4$ , in cold, it gives:

• A. trinitro glycerine
• B. dynamite
• C. glycerol trinitrate
• D. none of these

Answer 1

Answer: (C)

Glycerol, with cone. $HN{O}_3$ in cold, forms an ester i.e., glycerol trinitrate, which is used in making explosives, (like dyanamite, cordite etc.) $\underset{Glycerol}{\stackrel{C{H}_{2}OH}{\underset{C{H}_{2}OH}{\stackrel{|}{\underset{|}{\mathrm{CHOH}}}}}}+\underset{conc.Nitricacid}{3HO\cdot N{O}_2}\stackrel{conc.H_{2}S{O}_4}{\to }$ $\underset{Glyceroltrinitrate}{\stackrel{C{H}_{2}N{O}_2}{\underset{C{H}_{2}ON{O}_2}{\stackrel{|}{\underset{|}{CHON{O}_2}}}}}$
