Which one of the following is not present in the nitration mixture?
Options
- AN + O 2
- BHSO 4 -
- CSO 4 2 -

Correct answer
C. SO 4 2 -
Step-by-step solution
A mixture of concentrated nitric acid with organic or inorganic compounds containing NO 2 + ion is called nitration mixture. 2 H 2 SO 4   +   HNO 3   →   NO 2 +     +   H 3 O +   +   HSO 4 - So, SO 4 2 - ions are not present in nitration mixture.
