Question #0bff3

Answer 1

You might get `"1,3,5-trinitrobenzene."`

Explanation:

Conc. nitric acid and conc. sulfuric acid mixed together form the classic nitrating mixture that delivers the `NO_2^+` electrophile:

`H_2SO_4(aq) + HNO_3(aq) rarr H_2NO_3^(+) + HSO_4^-`

Sulfuric acid protonates nitric acid, which then spits out water and nitronium ion:

`H_2NO_3^(+) rarr H_2O + NO_2^(+)`

The nitronium ion, which is linear, is a potent electrophile, and will react with nucleophiles such as an aromatic ring.

`C_6H_5NO_2 + NO_2^(+) +HSO_4^(-) rarr 1,3-C_6H_4(NO_2)_2 +H_2SO_4`.

Another equiv of nitronium ion might give `1,3,5-C_6H_3(NO_2)_3`

The nitro group is a `"meta-director."`
