•Alkanes are saturated hydrocarbons because they have only single C-C bonds.
•General formula: CnH2n+2
•Reactions: Combustion & Substitution.]]> 2021-02-12 10:57:50 UTC https://padlet.com/nazeebnishan7305/gouqhg5q584hfnq2/wish/1195939226 Alkenes nazeebnishan7305 https://padlet.com/nazeebnishan7305/gouqhg5q584hfnq2/wish/1195941394
•Alkenes have a double bond.
•Alkenes are unsaturated hydrocarbons because they have a double C-C bond.
•General formula: CnH2n
•Eg: ethene, C2H4.
•Reactions: Combustion & Addition.
Alkenes undergo self addition in which alkene molecules join together to form long chains called polymers.
Example of an Alkene
Eg: ethene.
•Molecular formula:  C2H4
•Semi structural formula:  CH2 = CH2]]> 2021-02-12 10:58:47 UTC https://padlet.com/nazeebnishan7305/gouqhg5q584hfnq2/wish/1195941394 Alkynes nazeebnishan7305 https://padlet.com/nazeebnishan7305/gouqhg5q584hfnq2/wish/1195943774 •Have one triple bond between carbon atoms.
•Alkynes are unsaturated hydrocarbons because they a triple C-C bond.
•General formula: CnH2n-2
•Eg: ethyne, C2H2. (common name is acetylene)
•Reactions: Combustion & Addition.

•Eg: cyclohexane, C6H12.
•Saturated molecule: only single C–C bonds.
•Eg: benzene, C6H6.
•Unsaturated molecule: C to C bonds are equal to 1.5 bonds.
•There are 6 delocalised electrons.]]> 2021-02-12 10:59:50 UTC https://padlet.com/nazeebnishan7305/gouqhg5q584hfnq2/wish/1195943774
