Explanation:
When C6H4Br2(P) is treated with a mixture of concentrated HNO3 and concentrated H2SO4, it undergoes nitration. Mono nitration products are expected from this reaction.
Reasoning:
Therefore, when C6H4Br2(P) is treated with a mixture of concentrated HNO3 and concentrated H2SO4, three mononitration products are expected.
When C6H4Br2(P) is treated with a mixture of concentrated HNO3 and concentrated H2SO4, it undergoes nitration. Mono nitration products are expected from this reaction.
Reasoning:
- The presence of two bromine atoms in C6H4Br2(P) makes it less polar than its two polar isomers (ortho and para).
- When C6H4Br2(P) is treated with a mixture of concentrated HNO3 and concentrated H2SO4, it undergoes nitration.
- Because of the less polar nature of C6H4Br2(P), it is expected to react with nitric acid to form three mononitration products.
- The three possible mononitration products are:
- 2-nitro-1-bromobenzene
- 4-nitro-1-bromobenzene
- 2,4-dinitro-1-bromobenzene
Therefore, when C6H4Br2(P) is treated with a mixture of concentrated HNO3 and concentrated H2SO4, three mononitration products are expected.

Understanding the Compound
- The compound C6H4Br2(P) is a dibromo benzene. This means it has two bromine atoms attached to the benzene ring.
Understanding Isomerism
- The less polar isomer refers to the geometric arrangement of the bromine atoms on the benzene ring that results in less polarity.
- In the case of dibromo benzene, there are three possible geometric arrangements (ortho, meta, and para) but only ortho-dibromo benzene and para-dibromo benzene are polar. The less polar of the two is the para isomer.
Nitration Reaction
- Nitration is a general class of a chemical process for the introduction of a nitro group into an organic chemical compound.
- The nitration of benzene involves substitution of a hydrogen atom by a nitro group (-NO2) and this is facilitated by a mixture of concentrated nitric acid (HNO3) and sulfuric acid (H2SO4).
Mono Nitration Products
- Considering that the compound is para-dibromo benzene, the nitration can occur at any of the 4 remaining carbon atoms in the benzene ring.
- However, since the question asks for mono nitration products (meaning only one nitro group is added), the number of unique products will depend on the symmetry of the molecule.
- For para-dibromo benzene, the molecule is symmetric. Nitration at any of the 4 remaining positions will result in only 2 unique mono-nitration products due to this symmetry.
So, the answer is 2.
