(a)
Interpretation: The structure of the given compound para-toluidine has to be drawn.
Concept introduction:
To indicate relative position on a benzene ring, three terms are mainly used and they are,
- (1) Ortho-(o): On adjacent carbons (1,2)
- (2) Meta-(m): Separated by one carbon (1,3)
- (3) Para-(p): Separated by two carbons (1,4)
