Question

Aromatic amines are insoluble in water because of:

• A. the larger hydrocarbon part which tends to retard the formation of H-bonds.
• B. the smaller hydrocarbon part which tends to retard the formation of H-bonds.
• C. the larger hydrocarbon part which tends to increase the formation of H-bonds.
• D. none of these

Answer 1

The correct option is A the larger hydrocarbon part which tends to retard the formation of H-bonds.

Aromatic amines are insoluble in water because of large hydrocarbon part (hydorphobic) part which retards the formation of H-bonding. Lesser the H-bonding, lower is the solubility. Hence, the correct answer is option (a).
