When benzene is treated with concentrated

\mathrm{HN}{\mathrm{O}_3}

at room temperature it will give:

View answer and explanation

Correct option: C

Dark red colour

Option C (Dark red colour) is correct because benzene does not undergo nitration at room temperature, but the solution turns dark red due to the absorption of

\mathrm{N}{\mathrm{O}_2}

released by

\mathrm{HN}{\mathrm{O}_3}

In benzene, there is a delocalisation of π-electrons. Hence, each π-electron is attached by….carbon nuclei. Which statement is false? Assertion (A) In comparison to ethyl chloride, it is not easy to carry outnucleophilic substitution on vinyl chloride.

Reason (R) Vinyl group is an electron donating. If 2-oxopropanal and methanal are obtained by the reductive ozonolysis of compound (A), then the number of
