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

We need to evaluate the correctness of two organic reaction sequences presented in Statement I and Statement II.

Statement I:

The first sequence outlines the conversion of tetralin (a bicyclic hydrocarbon where a benzene ring is fused to a 6-membered aliphatic ring) into 1,2-diaminobenzene:

• Step (i) $$\text{KMnO}_4 / \text{H}^+$$ (Oxidation): Vigorous oxidation cleaves the aliphatic ring at the benzylic positions, converting both benzylic carbons into carboxylic acid groups. This yields phthalic acid (benzene-1,2-dicarboxylic acid).
• Step (ii) $$\text{NH}_3$$ (Ammonolysis & Heating): Reaction of phthalic acid with ammonia followed by heating forms phthalamide, which undergoes cyclization to give phthalimide.
• Step (iii) $$\text{Br}_2 + \text{KOH}$$ (Hoffmann Bromamide Degradation): Phthalimide undergoes Hoffmann degradation, converting the carbonyl-linked nitrogen groups into primary amines, yielding 1,2-diaminobenzene.

$$\implies \text{Statement I is True}$$

Statement II:

The second sequence outlines the synthesis of 3,5-dibromotoluene starting from 4-methylaniline (p-toluidine):

• Step (i) $$\text{Br}_2 / \text{H}_2\text{O}$$ (Electrophilic Aromatic Substitution): The strongly activating and ortho/para-directing $$-\text{NH}_2$$ group directs bromine atoms to both of its vacant ortho positions (positions 2 and 6), producing 2,6-dibromo-4-methylaniline.
• Step (ii) $$\text{NaNO}_2 + \text{HCl, } 0{-}5^\circ\text{C}$$ (Diazotization): The primary aromatic amine group ($$-\text{NH}_2$$) is converted quantitatively into a diazonium salt group ($$-\text{N}_2^+\text{Cl}^-$$).
• Step (iii) \text{aq. } $$\text{H}_3\text{PO}_2$$ (Deamination): Hypophosphorous acid reduces the diazonium group, replacing it with a hydrogen atom ($$-\text{H}$$), which results in the formation of 3,5-dibromotoluene.

$$\implies \text{Statement II is True}$$

Conclusion:

Both reaction sequences proceed successfully as described to form their respective major products.

Answer: Option C — Both Statement I and Statement II are true
