(a)

Interpretation Introduction

Interpretation: The structures of the major products when aniline is treated with the given set of reagents have to be drawn.

Concept Introduction:

An amino group present in an aromatic ring is ortho-para director.  It directs the entering group into two ortho-positions and one para-position that depends on the nature of the reagent.

To find: Draw the structure of the major product when aniline is treated with the given reagent (a)

Find the director of amino group

(b)

Interpretation Introduction

Interpretation: The structures of the major products when aniline is treated with the given set of reagents have to be drawn.

Concept Introduction:

Acetylation is the reaction in which acetyl group is introduced in the reactive center of the compound.  In most cases, bases are used as the reagents.

To find: Draw the structure of the major product when aniline is treated with the given reagent (b)

Find the nature of aniline and pyridine

(c)

Interpretation Introduction

Interpretation: The structures of the major products when aniline is treated with the given set of reagents have to be drawn.

Concept Introduction:

When excess methyl iodide is treated with the amine group containing compound, that amine group undergoes exhaustive alkylation to give a quaternary ammonium salt.

Find the reactive group in aniline for the reagent (c)

(d)

Interpretation Introduction

 Interpretation: The structures of the major products when aniline is treated with the given set of reagents have to be drawn.

Concept Introduction:

When aniline is treated with NaNO2 and HCl, the corresponding diazonium salt is formed which is an intermediate for the transformation of various functional groups.
