Alkynes and Organic Synthesis
Alkynes: organic compounds containing a carbon-carbon triple bond
1. Similar to naming of alkanes and alkenes, review p80-85, 173-175
no (E, Z) isomerism as in alkenes
2. Suffix: -yne
3. More than on
Alkyl Halides: Nomenclature
Similar to naming alkanes, treat halogen as a substituent
Find parent chain, include double or triple bond
if there is any
Number parent chain from the
Alcohols and Phenols
Naming of alcohols and phenols
a. Longest chain containing OH as parent chain;
b. Number parent chain from the end nearer to OH
c. Name substituents and arrange them in alphabetical order
Ethers and Epoxides;
Thiols and Sulfides
Ethers and their naming
A. Alkyl ethers:
alkyl alkyl ether
alkoxy in presence of other functional groups.

Ethers and the
Structure and Bonding
Why should we study Org Chem?
the study of carbon compounds
The basis of understanding life and living things
- all molecules involved in life: DNA/RNA, proteins, sugar, etc
- metabolism: sugar to CO2 + H2O + energy
Polar Covalent Bonds;
Acids and Bases
Polarity in covalent bonds: electronegativity (EN)
Nonpolar covalent bond
Electronegativity (EN): the intrisic ability of an atom to attract the shared
electrons in a covalent bond.
Polarity in covalent bond
Alkanes, Cycloalkanes, &
Containing only C and H
General formula: CnH2n+2.
n = any integer
sp3- C, only C-C and C-H.
Waxy: or aliphatic compounds
Straight-chain (or normal) alkanes
Stereochemistry at Tetrahedral
A new form of isomerism: Chirality
Definition: an object not superimposable with its
mirror image is chiral.
This property of the object is called chirality
Chirality in Organic
Organic Reactions: Mechanism,
Energy, Intermediates, and
How many kinds of organic reactions?
1. Addition reactions: two molecules merge into one
2. Elimination reactions: one molecule break into two, often
resulting in a small molecule
Structure and Reactivity
Alkenes: hydrocarbons containing one or more C=C bonds
