Question

Write structural formulas for these amines. (a) Isobutylamine (b) Triphenylamine (c) Diisopropylamine

Short answer

Question: Draw the structural formulas for the following amines: (a) isobutylamine, (b) triphenylamine, and (c) diisopropylamine. Answer: (a) Isobutylamine: (CH3)2CH-CH2-NH2; (b) Triphenylamine: N(C6H5)3; (c) Diisopropylamine: N((CH3)2CH)2

Step-by-step solution

Know what an amine is

An amine is an organic compound derived from ammonia (NH3) by replacing one or more hydrogen atoms with organic groups (alkyl or aryl groups). The general formula of amines is R-NH2, where R is an alkyl or aryl group.

Identify the groups in each amine

(a) Isobutylamine: "Isobutyl" refers to an isobutyl group (CH3)2CH-CH2-. (b) Triphenylamine: "Triphenyl" refers to three phenyl groups (C6H5) attached to a nitrogen atom. (c) Diisopropylamine: "Diisopropyl" refers to two isopropyl groups (CH3)2CH- attached to a nitrogen atom.

Draw the structural formula for isobutylamine

For isobutylamine, replace one hydrogen atom in ammonia (NH3) with an isobutyl group (CH3)2CH-CH2-: isobutylamine: (CH3)2CH-CH2-NH2

Draw the structural formula for triphenylamine

For triphenylamine, replace three hydrogen atoms in ammonia (NH3) with three phenyl groups (C6H5): triphenylamine: N(C6H5)3

Draw the structural formula for diisopropylamine

For diisopropylamine, replace two hydrogen atoms in ammonia (NH3) with two isopropyl groups (CH3)2CH-: diisopropylamine: N((CH3)2CH)2
