Amines and Amides

Amines
-have a nitrogen with carbon bonded to it


Amides
-Amides are used in nylon, kelvar, penicillin, proteins, LSD

Esters, Carboxylic Acids, Aldehydes

REVIEW from last class
Alcohols
R-OH


ketones
R=O


ethers
R-O-R1(doesn't have to be the same)


halidea
R-F, R-Cl, R-Br


NEW STUFF!!!


Aldehydes -change ending to '-al'
-attach a double bonded oxygen and a hydrogen to either end of the carbon chain


Carboxylic acids
-found in insect bites
-building blocks of fats/steroids
-change ending to '-oic'
-attach a double bonded oxygen and a hydroxide to either end of the carbon chain


Esters
-used as artificial flavoring for purfumes, synthetic fibers
-source of odour/flavour in fruits
-name the primary R with a -yl ending
-name the secondary R with -ate ending
-esters are formed through esterfication
- react a carboxylic acid with an alcohol

Functional Groups

Today we had a quiz! Also we learnt about functional groups.

1) Halides
- Group 17 elements
-bromine(bromo), chlorine(chloro), fluorine(floro)
-you use this when you see bromine, chlorine or fluorine as a side chain to your carbon chain

2) Alcohols
- have an OH(hydroxyl) function group
-same rules as usual but change the ending to '-ol'

3) Ethers
-there is an oxygen atom between two carbon chains
-use side chain endings(-yl) for both chains followed by ether

4) Ketones
-double bonded oxygen
-change the ending to '-one'

Alkynes/ Cis and Trans/ Alycyclics/ Aromatics

Alkynes (triple bonds)
-use -yne ending after parent chain
-number using lowest possible number

Cis and Trans
-side chains cannot rotate around double bonds
-cis: same side of side chain
-trans: opposite side of side chain

Alycyclics
-all the same naming rules apply
-add cyclo- to the name of the parent chain

Aromatics
-cyclohexene can have double bonds in its ring



wow okay this guy is kinda weird but he does a prett good job of explaining it so ill let him do so!

Continutation of Organic Chemistry

B. ALKENES (double bonds)
1. All the same rules for naming appy
2. Use the correct prefix and -ENE ending
3. Identify the location of the double bond using carbon numbers

Here is a website you can use to practice, the answer are here too!
http://www.sciencegeek.net/APchemistry/APtaters/alkanes.htm

C. TRIPLE BONDS
1. Use the -YNE ending

For some more detailed notes, here's a link to an online tutor!!

ORGANIC CHEMISTRY



- Organic Chemistry is the study of the carbon atom and its compounds.

- carbon compounds outnumber all other compounds combined.....
> carbon can form many different bonds
> the can have different arrangements
> can form long chains of carbon atoms

HydroCarbon Hierarchy - click here for a more in depth look


There are 3 types of chemical formulas
1) Molecular - eg C3H8
2) condensed structural - eg
CH3-CH2-CH3
3) structural






Isomers
One molecular formula can represent several different compounds. These are called isomers
EG Alkanes

1. circle the largest carbon chain. name the chain with the appropriate prefix ane ending

2. locate any side chains by numbering the carbon chain. use lowest possible #s

3. name the side chain with appropriate prefix and yl ending

4. if there are more than one of the same alkyl side chain add the multiplier in front of the branch name
