1
What is the name and molecular formula of the first ALKANE?
 
Methane. CH4
2
What is the name and molecular formula of the ALKENE containing just 2 carbons?
 
Ethene C2H4
3
What is a hydrocarbon?
 
A compound made up of the elements Hydrogen and Carbon ONLY!
4
Identify the family (homologous series) that this compound belongs to and name it: C4H10
 
Alkane Butane
5
What is an "saturated" molecule?
 
One containing only single bonds between carbon atoms.
6
What chemical would you use to distinguish between ethane and ethene?
 
Bromine
7
In Question 6, what colour change would be observed in the case of using ethene?
 
From orange/brown to colourless
8
Name the product of the reaction between ethene and bromine
 
1,2-dibromoethane
9
What kind of reaction converts ethene into polythene (polyethene)?
 
Polymerization
10
Define the term "addition polymer".
 
A large (giant) molecule formed from many small unsaturated molecules joining together
11
Apart from the length of the molecule, what striking difference is noted between the addition...
 
The polymer does not have C=C bonds
12
If one of the 4 H atoms of ethene is replaced by a Cl atom we get a different polymer. Name...
 
Polyvinylchloride (PVC) In modern terms it is also called Polychloroethene
13
If one of the 4 H atoms of ethene is replaced by a CH3 group we get a different polymer. Name...
 
Polypropylene
14
If one of the 4 H atoms of ethene is replaced by a C6H5 group we get a different polymer. Name...
 
Polystyrene
15
What is happening in this reaction: H2C=CH2 + H2O = CH3CH2OH
 
Ethene is being converted to industrial alcohol (ethanol)
16
As you move from one member of a family or organic compounds to the next highest, how does...
 
There is a steady increase. This is called a gradation in physical properties.
17
Define the term "homologous Series"
 
A family of organic compounds that share the same general formula, have similar chemical properties...
18
What is the main component of Natural Gas (North Sea gas)
 
Methane
19
What are the main componenets of LPG Liquid Petrolem Gas
 
Propane and butane
20
What is the liquid used in most cigarette kighters
 
Hexane
