Introduction

• Organic Chemistry
• Living Chemistry
• Carbon Chemistry
• 2.2 million organic compounds
• Because Carbon (C) can bond to itself
• Polymers are a subset of organic compounds

3
Alkanes

• Tetrahedral
• Always have 4 bonds
• Covalent
• Simplest is methane
• Hydrogen Carbon Hydrocarbon
• Isomers

4
Carbon Compounds
Resource Section of webpage has Sec V Roots and
Substituent Groups with names
5
Alkenes

• Double Bonds!
• One double bond ex. ethene
• Two double bonds ex. Butadiene
• Saturated
• Unsaturated
• Polymer building block

6
Alkynes

• Triple Bonds!
• CC-H
• CC-CC name?
• Note The structural formula of the monomer shows
  the properties of the polymer.

H
It takes Alkynes to make a world!
7
Rings

• What if double ring caps?
• Cyclic Alkane
• Cyclic Alkenes also called Aromatic
• Example Benzene

Benzene
8
xygen Containing Compounds

• Aldehydes
• Double bonded Oxygen in the end of the molecule
• Ketones
• Double bonded Oxygen at the middle of the
  molecule

• Alcohols

9
xygen Containing Compounds

• Ether (ether)
• Alcohol Alcohol Ether Water
• Ester (-oate)
• Acid Alcohol Ester Water

• Acid
• ioc acid
• Diacid

10
itrogen Containing Compounds

• Simple Amine

• Aminos

Why do chemists like nitrates so much? Theyre
cheaper than day rates!
Amine Acid Amide Water HCOOH HN(CN3)2
? HCON(CH3)2 H2O formic acid
dimethylamine dimethyl formamide
