LAB 8

Are derivatives of ammonia NH 3

Contain N attached to one or more alkyl or
aromatic groups

Amines are classified as

Amines are named as

The boiling points of amines are _____ than alkanes.
_____ than alcohols of similar mass.

Amines are _____
If they have 1-5 carbon atoms.

Amines React as

Neutralization of acid forms

An ______ Forms when an amine is neutralized by acid.
Is named by replacing the amine part of the name with
ammonium followed by the name of the negative ion.

are classified according to the number of
carbon atoms bonded to the nitrogen atom.

test for the detection and distinction of primary,
secondary, and tertiary amines in a given
sample.

The reaction of the benzene sulfonyl chloride with primary
amines gives a sulfonamide product that is

The reaction of the benzene sulfonyl chloride with secondary
amines gives a sulfonamide product that is

No such reaction occurs between a
tertiary amine and the benzene sulfonyl
chloride reagent. Tertiary amines help
in the hydrolysis of sulfonyl chloride.
This reaction yields salts that are
soluble in water.

A test that reacts with aryl and aliphatic
amines in an aqueous or ethanolic
medium that will give different colors
depending upon the nature of the
amine, i.e. primary, secondary or
tertiary amine.

Nitro substituted amines cannot be
detected, while phenylenediamine
gives

is commonly used to differentiate
between primary and secondary
aliphatic amines (amines where
aromatic rings are not directly attached
to the nitrogen atom).
(+) – red color (primary amines)
