Each of the amine has to be classified as primary, secondary, or tertiary amine and as aliphatic or aromatic . Concept introduction: In chemistry Structure is the arrangement of chemical bonds between atoms in a molecule, specifically which atoms are chemically bonded to what other atoms with what kind of chemical bond. Amines are the derivatives of ammonia ( N H 3 ) with one or more of the hydrogens replaced with a substituent such as an alkyl group. Depending on the number of carbon side chain of the amide, different types of amides can form. If nitrogen atom in amine group is attached only to alkyl groups, then it is an aliphatic amine. If nitrogen atom in amine group is attached to at least one aryl groups, then it is an aromatic amine. If nitrogen atom in amine group is a part of an aromatic ring, then it is a heterocyclic aromatic amine.

Question

Chapter 23, Problem 23.18P

(a)

Interpretation Introduction

Interpretation:

Each of the amine has to be classified as primary, secondary, or tertiary amine and as aliphatic or aromatic.

Concept introduction:

In chemistry Structure is the arrangement of chemical bonds between atoms in a molecule, specifically which atoms are chemically bonded to what other atoms with what kind of chemical bond.

Amines are the derivatives of ammonia (NH3) with one or more of the hydrogens replaced with a substituent such as an alkyl group.

Depending on the number of carbon side chain of the amide, different types of amides can form.

If nitrogen atom in amine group is attached only to alkyl groups, then it is an aliphatic amine.

If nitrogen atom in amine group is attached to at least one aryl groups, then it is an aromatic amine.

If nitrogen atom in amine group is a part of an aromatic ring, then it is a heterocyclic aromatic amine.

For the compound: C8H17NO2 Use the following information to come up with a plausible structure: 8 This compound has "carboxylic acid amide" and ether functional groups. The peaks at 1.2ppm are two signals that are overlapping one another. One of the two signals is a doublet that represents 6 hydrogens; the other signal is a quartet that represents 3 hydrogens.
