Write the structural formula of: (a) o-ethylanisole (b) p-nitroaniline (c ) 2, 3-dibromo-1-phenylpentane (d) 4-ethyl-1-fluoro-2-nitrobenzene |
Answer» Solution :(a) o-Ethylanisole: `C_(6)H_(5)OCH_(3)` its common name is anisole. So  Note: Generally the substitute ortho positions written in left side. (b) p-nitroaniline: Aniline MEANS `C_(6)H_(5)NH_(2) and -NO_(2)` is at pera position so, `NO_(2) - C_(6)H_(4)- NH_(2)`  (c ) 2, 3-dibromo-1-phenylpentane : In this five carbon containing parent chain, the PHENYL, bromo and bromo substitutes are present at 1, 2 and 3 position respectively and written as under `overset(5)C - overset(4)(C )-underset(underset(Br)(|))overset(3)(C )- underset(underset(Br)(|))overset(2)(C )- underset(underset(C_(6)H_(5))(|))overset(1)(C )`  (d) 4-ethyl-1-fluoro-2-nitrobenzene:
