What are hydrocarbons?
|
Organic comping that contain carbon and hydrogen only
|
|
|
What is a saturated hydrocarbon?
|
A hydrocarbon with single bonds only
|
|
|
What is an unsaturated hydrocarbon?
|
A hydrocarbon containing carbon to carbon multiple bonds.
|
|
|
What is an aliphatic hydrocarbon?
|
A hydrocarbon with carbon atoms joined together in straight or branched chains
|
|
|
What is an alicyclic hydrocarbon?
|
A hydrocarbon with carbon atoms joined together in a ring structure
|
|
|
Why can carbon form so many compounds?
|
A carbon atom can form bonds witb other carbon atoms to make chains and rings.
A carbon atom can form a single double or triple bond to another carbon atom. A carbon atom can bond with atoms of other elements such as oxygen hydrogen nitrogen phosphorus and the halogens. |

What is a functional group?
|
The part of the organic molecule responsible for its chemical reactions
|
|
|
What is a homologous series?
|
A series of organic compounds with the same functional group but with each successive member differing by CH2
|
|
|
What are alkanes?
|
The homologous series with the general formula CnH2n+2
|
|
|
What are the properties of a homologous series?
|
They contain the same functional group
They have similar chemical properties Each successive member of a homologous series differs by one carbon and two hydrogen atoms. |
|
|
Describe the bonding in alkanes
|
Alkanes are saturated straight chained hydrocarbons with single carbon to carbon bonds. Each carbon atom is bonded to four other atoms and has a tetrahedral shape with a bond angle of 109.5°.
|
