How do you name alkane groups?
Alkane groups will look sort of like some of the alkanes themselves, CH4, methane for example, except that the group will be missing an H where it is attatched to the principal chain. To name the group you would use the name of the alkane but change the "ane" to "yl". In this case the methane as an alkyl group is names "methyl".
Ethane becomes ethyl, butane becomes butyl, etc.
