for the compound 3-methyl-hex-2-enol , alkene is also considered as functional group but how???
The functional groups are methyl, alcohol and alkene groups.
3-methyl-hex-2-
enol is an alkene consisting of two OH groups of atoms. The fact that it is an
enol makes it an alkene.
Otherwise it would have been simply said to be 3-methyl-hex-2-
anolJust like for hexene and hexane.
Hexene is an alkene while hexane is an alkane. For this compound, it contains two OH groups each from the 1 carbon forming the carbon-carbon double bond.
Hope it helps
