Chemistry Question from JEE Main 2026 · 23 January, Shift 2

Given below are two statements:

Statement I: The compound

Benzene ring carrying an $$-NH_2$$ group on each of two adjacent carbons, i.e. benzene-1,2-diamine (ortho-phenylenediamine).

can be synthesized from

Benzene ring carrying a $$-CH_2CH_2CH_3$$ (n-propyl) group on each of two adjacent carbons, i.e. 1,2-di-n-propylbenzene.

using simpler reagents in the order (i) Acidic KMnO4KMnO_4, (ii) Ammonia, (iii) Bromine and alkali.

Statement II: 4-Methylaniline (p-toluidine) can be converted into 3,5-dibromotoluene using reagents in the order (i) Bromine–H2OH_2O, (ii) NaNO2NaNO_2/HCl (0−5 ∘C0-5\,^\circ\text{C}), (iii) Aq. H3PO2H_3PO_2.

In the light of the above statements, choose the correct answer from the options given below:

  • A

    Statement I is false but Statement II is true

  • B

    Both Statement I and Statement II are false
