Chapter 2

An Introduction to

Organic Compounds

Functions, Nomenclature,

Physical Properties,

and

Conformations

Adapted from Profs. Turro & Breslow, Columbia University and Prof.Irene Lee,

Case Western Reserve University


Common Functional Groups

ClassGeneral Formula

Halohydrocarbons RX

Alcohols R

Ethers RR

Amines


Nomenclature of Alkyl Halides

In the IUPAC system, alkyl halides are named as substituted

alkanes




Nomenclature of Ethers

As substituents:

???



Nomenclature of Alcohols

  • In an alcohol, the OH is a functional group

  • A functional group is the center of reactivity in a

  • molecule

1. Determine the parent hydrocarbon containing the functional

group


2. The functional group suffix should get the lowest number

3. When there is both a functional group suffix and a substituent,

the functional group suffix gets the lowest number



Nomenclature of Amines are cited

  • The substituents are listed in alphabetical order and a number or

  • an “N” is assigned to each one




Other are citedCommon Functional Groups

ClassGeneral Formula

Aldehydes

Ketones

Carboxylic Acids

Esters

Amides


Attractive Forces are cited

Ionic bonds

Covalent bonds

Hydrogen bonds

Dipole–dipole interaction

Ion-dipole

Dispersion

Forces

van der Waals force

  • The greater the attractive intermoleclar forces between molecules, the higher is the boiling point of the compound, eg. water.


Protein Shape: Forces, Bonds, Self Assembly, are cited

Folding (Intramolecular forces)

Ion-dipole

(Dissolving)

40-600kJ/mol

10-40kJ/mol

150-1000kJ/mol

0.05-40kJ/mol

700-4,000kJ/mol


  • What organic functions can have hydrogen bonding?


Dipole–Dipole Interaction are cited

Dipole–dipole interactions are stronger than van der

Waals force but weaker than ionic or covalent bonds


van der Waals Forces are cited

Boiling and melting points of a compound increases with the increase in van der Waals force


Ion-Dipole & Dipole-Dipole Interactions: are cited

like dissolves like

  • Polar compounds dissolve in polar solvents

  • & non-polar in non-polar
