How does names of alkanes end?
- ane
First 10 alkanes
Methane
Ethane
Propane
Butane
Pentane

Decane
Difference between alkanes and alkenes?
In Alkenes one or more Carbon has a double bond
General formula for alkenes
CnH2n
First alkene
Ethene C2H4
Difference between alkynes and alkenes?
In alkynes there is a triple bond
General formula for alkyne
CnH2n-2
Simplest alkyne
Ethyne, C2H2
How does the ending in alkenes & alkynes vary with number of double or triple bonds
Number of bonds is put in front, ex: - triyne or - diene
What are alkyl groups
Attachment of a Carbon-hydrogen group to the main chain
How do you indicate in the name that a compound is cyclic?
Add cyclo in front
How does the functional group of ethers look?
R-O-R
How do you name an ether?
Alkyl-oxy- alkane
Ending of amines when naming them
-Anamine
What is the functional group of amines?
-NH2

How do you name an arene?
Alkyl + benzene
What is the functional group of aldehydes?
Carbonyl: -CHO
What is the name ending of aldehydes?
- Anal
What is the functional group of ketones?
Carbonyl: R-CO-R
Name ending of a ketone
-Anone
How does a ketone & an aldehyde differ?
On a ketone the carbonyl group is in the middle & on a aldehyde it is at one of the ends
Name ending for carboxylic acids
-Anoic acid
What is the functional group of carboxylic acids?
Carboxyl: -COOH
What is the functional group of alcohols?
Hydroxyl: OH
Name ending for alcohols

What is a primary alcohol?
Alcohol where the carbon that the OH group is attached to is only attacked to one Carbon
What does primary alcohols turn into when oxidised? & what can that be oxidised to?
Aldehyde → carboxylic acid
What are secondary alcohols?
Alcohols where the Carbon attached to the OH group is attached to 2 Carbons
What does secondary alcohols turn into when oxidised?
Ketones
What does tertiary alcohols turn into when oxidised?
Nothing, can’t be oxidized
What are tertiary alcohols?
Alcohols where the Carbon attached to the OH group is attached to 3 Carbons
How do you name an ester?
Alkyl + anotate
What is the functional group of esters?
Ester: R-COO-R
What are structural isomers?
2 or more molecules that have the same formula but different structure
What is important to remember regarding isomers with double bonds?
Rotation around a double bond is restricted
What is functional group isomer?
Same molecule formula but different functional groups
What can alcohol have a structural isomer with where the functional group has changed?
Ether
What can aldehydes have a structural isomer with where the functional group has changed?
Ketones
What can canboxylic acid have a structural isomer with where the functional group has changed?
Ester
What is stereoisonerism?
Same structural formula but different spatial arrangement of atoms
Where is cis-trans isomerism found?
Alkenes and cyclic compounds
In cis isomers, where are the groups found?
On the same side
In trans isomers, where are the groups found?
Opposite sides
What is needed for cis-trans isomerism to occur?
2 different atoms or groups of atoms bonded to each carbon atom in the double bond
Does double bond allow for rotation?
No
Where are the groups located in cis isomers?
Same side
Where are the groups located in trans isomers?
Opposite side
Different name for cis-trans isomers
Geometric isomers
Is there a alcohol in carboxylic acid?
No!
