Chapter E, Problem E.21P

Interpretation Introduction

(a)

Interpretation:

Whether the amine given in Problem E.20 (a) is primary, secondary, or tertiary is to be determined.

Concept introduction:

Amines are classified as primary ${\text{(1}}^{\text{o}}\text{)}$, secondary ${\text{(2}}^{\text{o}}\text{)}$, or tertiary ${\text{(3}}^{\text{o}}\text{)}$ according to the number of alkyl/aryl groups attached to the N atom. In a primary amine, the N atom is bonded to one alkyl or aryl group. In a secondary amine, the N atom is bonded to two alkyl or aryl groups. In a tertiary amine, the N atom is bonded to three alkyl or aryl groups.

Interpretation Introduction

(b)

Interpretation:

Whether the amine given in Problem E.20(b) is primary, secondary, or tertiary is to be determined.

Concept introduction:

According to the number of alkyl/aryl groups attached to the N atom, the primary, secondary and tertiary amines are classified. In a primary amine, the N atom is bonded to one alkyl or aryl group. In a secondary amine, the N atom is bonded to two alkyl or aryl groups. In a tertiary amine, the N atom is bonded to three alkyl or aryl groups.

Interpretation Introduction

(c)

Interpretation:

Whether amine given in Problem E.20(c) is primary, secondary, or tertiary is to be determined.

Concept introduction:

According to the number of alkyl/aryl groups attached to the N atom, the primary, secondary and tertiary amines are classified. In a primary amine, the N atom is bonded to one alkyl or aryl group. In a secondary amine, the N atom is bonded to two alkyl or aryl groups. In a tertiary amine, the N atom is bonded to three alkyl or aryl groups.

Interpretation Introduction

(d)

Interpretation:

Whether the amine given in Problem E.20(d) is primary, secondary, or tertiary is to be determined.

Concept introduction:

According to the number of alkyl/aryl groups attached to the N atom, the primary, secondary and tertiary amines are classified. In a primary amine, the N atom is bonded to one alkyl or aryl group. In a secondary amine, the N atom is bonded to two alkyl or aryl groups. In a tertiary amine, the N atom is bonded to three alkyl or aryl groups.

Interpretation Introduction

(e)

Interpretation:

Whether the amine given in Problem E.21(e) is primary, secondary, or tertiary is to be determined.

Concept introduction:

According to the number of alkyl/aryl groups attached to the N atom, the primary, secondary and tertiary amines are classified. In a primary amine, the N atom is bonded to one alkyl or aryl group. In a secondary amine, the N atom is bonded to two alkyl or aryl groups. In a tertiary amine, the N atom is bonded to three alkyl or aryl groups.
