In an alkene with two carbon atoms being joined, there would be one double bond between the carbon atoms, and 4 single bonds for the 4 hydrogens, and it would be drawn as follows: H2-C=C-H2. This is ethene, and so it has a total of 5 bonds (unless you count the double bond as a sigma and a pi) then it has 6 bonds.
Alkanes have a single bond, and Alkenes have a double bond. The general form for Alkenes is CnH(2n)
Saturated
Single and double
Organic
Examples are oxygen, nitrogen , alkenes with carbon carbon double bonds, alkynes with carbon carbon triple bonds, the carbon oxygen double bonds in carbon dioxide
Olefins or alkenes
No, they are unsaturated as they contain double bonds
alkenes
Alkanes have a single bond, and Alkenes have a double bond. The general form for Alkenes is CnH(2n)
The difference between an alkane and an alkene is that: Alkanes have only single bonds between carbon atoms and are said to be saturated: when put in bromine water, the bromine water stays orange - formula: CnH2n+2; Alkenes: have one or more double bond(s) between carbon atoms and are unsaturated: when put in bromine water, the bromine water turns clear - formula: CnH2n.
Saturated
Single and double
If the compounds only contain carbon and hydrogen, they are called alkanes.
Organic
Alkenes are hydrocarbons containing carbon-carbon double bonds. There are several different names for alkenes. Some examples are butane, pentene and octadiene.
Alkanes have ordinary covalent single carbon-carbon bonds and carbon-hydrogen bonds. Alkenes have double carbon-carbon bonds.
Examples are oxygen, nitrogen , alkenes with carbon carbon double bonds, alkynes with carbon carbon triple bonds, the carbon oxygen double bonds in carbon dioxide
