Organic alkene
* Alkenes are aromatics and are important builder molecules
  - liquid and spoil easily
  - nucleophilic because they are electron-rich
  - similar to alkanes
  - the starting material for many different chemicals
  - burn in air or oxygen, as do alkanes
  - follow the same naming convention used for alkanes
  - have p electrons availble to share with electron-poor electrophiles
  - normally react as nucleophiles by sharing their p electrons
  - serve as intermediates in the preparation of a variety of organic compounds
  - undergo addition reactions usually by electrophilic reagents
* An alkene is an organic compound
+ Hydrocarbon, Hydrocarbon "Families", Alkenes
  * Alkenes are similar to alkanes. The main difference between them is that alkenes have a carbon to carbon double bond. The general formula for the alkenes is CnH2n.
+ Hydrogenation: Chemistry
  * Vegetable oils have alkenes in them. Alkenes are liquid and spoil easily. People making shortening add hydrogen to the alkene, turning it into an alkane. The alkanes are more solid and stable. A catalyst is used to react the hydrogen with the oil. This makes trans fats, though. Margarine is an example of a hydrogenated spread.

Organic alkyne
* Alkynes are also easy to reduce to double bonds
  - hydrocarbons
  - insoluble in water but are soluble in organic liquids
  - linear and alkanes are tetrahedral
* Alkynes are more reactive than the alkanes or alkenes due to the presence of unsaturated bonds
  - their alkene and alkane counterparts
  - usual hydrocarbons
  - have a carbon to carbon triple bond
* An alkyne is an organic compound
  * Alkynes are more reactive than usual hydrocarbons. For example, they are more reactive than alkenes in many reactions. If the alkyne is at the end of a molecule, it is easy to remove the proton with a strong base. Then, the alkyne can be used in addition reactions. For example, it can be added to a ketone. Alkynes are also easy to reduce to double bonds.

Alkynes are also easy to reduce to double bonds. They can be made into both 'trans' and 'cis' double bonds. Alkynes are also used a lot in pericyclic reactions.
+ Hydrocarbon, Hydrocarbon "Families", Alkynes
  * Alkynes have a carbon to carbon triple bond. CnH2n-2 is their general formula.

Organic amide
* Amides are made from carboxylic acid groups and amine groups through the loss of water
  - non-migratory slip additives
  - can also be active, but their activity depends on the overall structure
  - made by deprotonating ammonia are very strong bases
  - undergo hydrolysis in acidic conditions to yield a carboxylic acid and an amine salt
* An amide is an organic compound
+ Amide, Amides in inorganic chemistry: Nitrogen compounds :: Functional groups
  * An 'amide' ion is different from an amide in organic chemistry. The amide ion is made by deprotonating ammonia. This is ammonia acting as an acid, although a very weak one. Amides made by deprotonating ammonia are very strong bases. Sodium amide is an example.
