Among the following statements on the nitration of aromatic compounds, find the number of false statement(s)? i) The rate of benzene is almost the same as that of hexadeuterobenzene. ii) Loss of aromaticity when overset(oplus)NO_2 attacks at ortho and Para position and not at Meta position. iii) Nitrobenzene prepared from benzene by using a mixture of conc. HNO_3 and conc. H_2SO_4 in which HNO_3 act as a base iv) Nitration is an electrophilic substitution reaction.

A : HNO_(2) acts as reducing agent only. R : HNO_(2) oxidises to HNO_(3) only but not reduce by any reducing agent.

Give reasons for the following: (1) HNO_3 acts only as an oxidising agent while HNO_2 can act both as a reducing agent and an oxidising agent (2) Chlorine liberates iodine from Kl solution.

Explain the following giving reason why HNO_3 can act as oxidising agent only while HNO_2 can act as both oxidising and reducing agent .

HNO_(2) acts both as reductant and as oxidant, while HNO_(3) acts only as oxidant. It is due to their
