Hydrocarbons are made up of carbon and hydrogen atoms.
Alkanes are a group of Hydrocarbons. They have saturated covalent bonds.
They are made up of a string of carbon atoms joined by single carbon bonds, surounded by hydrogen atoms so each carbon atom has four single carbon or hydrogen bonds. H H H
They are unreactive because the C-C C-H bonds are unreactive. H C C C H
The first 4 alkanes are H H H
- methane CH4
- ethane C2H6
- propane C3H8
- butane C4H10
The formula for alkanes are CnH2n+2
Alcohols have an -OH functional group which gives them their characteristic properties.
The first two alcohols are:
- Methanol CH3OH
- Ethanol C2H5OH
The formula for alcohol is: CnH2n+1OH
methanol is used in manufacture of fuels, adhesives, foams, cosmetics and solvents.as an important chemical feed stock.
Ethanol is used as a solvent, fuel and alcholic drink component.
