Question

What function does nitric acid do in the reaction of benzene with I 2 to produce iodobenzene? (A) HNO 3 converts I 2 to HI (B) It acts as a catalyst (C) HNO 3 converts I to I 2 (D) It oxidizes I2 to I+

HNO 3 oxidises the by-product HI (i.e. .I-) to I 2, otherwise it reduces the product iodobenzene back to benzene.

Q. What function does nitric acid do in the reaction of benzene with $I_{2}$ to produce iodobenzene?

$H N O_{3}$ converts $I_{2}$ to $H I$

It acts as a catalyst

$H N O_{3}$ converts $I$ to $I_{2}$

It oxidizes $I_{2}$ to $I^{+}$

$H N O_{3}$ oxidises the by-product $H I$ (i.e. $I^{-})$ to $I_{2}$ , otherwise it reduces the product iodobenzene back to benzene.

Q. What function does nitric acid do in the reaction of benzene with I2​ to produce iodobenzene?

HNO3​ converts I2​ to HI

It acts as a catalyst

HNO3​ converts I to I2​

It oxidizes I2​ to I+

HNO3​ oxidises the by-product HI (i.e. I−) to I2​, otherwise it reduces the product iodobenzene back to benzene.
