Nitration of propane with nitric acid vapor at about `430^(@)C` is expected to yield
(i) `1`-nitropropane
(ii) `2`-nitropropane
(iii) nitroethane
(iv) nitromethane

Options

A. (i), (ii)
B. (iii), (iv)
C. (i), (ii), (iii),(iv)
D. (ii)

Answer

C

Explanation

At ordinary temperatures, alkanes do not react with `HNO_(3)`. However, when a mixture of an alkane and fuming `HNO_(3)` vapors is heated at `423-673K` under pressure (vapor phase nitrogen), alkanes undergo nitration giving a mixture of nitroalkanes resulting through the substitution of different types of `H` atoms as well as the cleavage of `C-C` bonds.
