324326 Assertion :
Aliphatic hydrocarbons undergo nitration easily with conc. \(\mathrm{HNO}_{3}\) in vapour phase not with nitrating mixture.
Reason :
As alkanes do not have delocalized \(\pi\)-electron cloud to attract positively charged nitronium ion.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
