properties of H.C
alkenes
low solubility in water
more reactive than alkalis
nonpolar
end with -ene
at least 1 double bond between c-c
general formula: CnH2n
alkanes
all bonds between c are single bonds
end with - ane
general formula CnH2n+2
physical properties of alkanes:
low melting and boiling points compared to polar molcules of same molar mass
methane molecules have little intermolecular attraction compared to water
all bonds are non polar
chemical properties of alkanes
low reactivity because they are non polar and have no charge
alkynes
have physical and chemical properties similar to alkenes but are generally more reactive
end with -yne
at least 1 triple bond
general formula: CnH2n-2
Reactivity: alkynes>alkenes>alkanes
