Differentiation between Alkanes, alkenes, alkynes
Alkanes
All bonds between c are single bonds
Names end with -ane
General Formula: CnH2n+2
Physical properties of Alkanes
All bonds in alkanes are non polar
Have low melting and boiling point compared to polar molecules of some molar mass
methane molecules have little intermolecular attraction
chemical properties of alkanes
have low reactivity
Alkenes
There at least 1 double bond between c-c
end with -ene
Gernal formula: CnH2n
Properties of alkene
Alkenes are non polar have low soluibility in water
Alkenes are more reactive than alkenes
Alkynes
at least 1 triple bond
end with -yne
vernal formula: CnH2n-2
Properties of alkynes
Alkynes have physical and chemical properties similar to alkenes that are generally more reactive
