The carbons and oxygens of the carboxylic acid functional group are red. (B) This is the structure of oleic acid, an 18-carbon unsaturated fat. The carbons of the alkene functional group ...

This causes a smoky flame. Alkenes have a functional group C=C – the part of the molecule that takes part in reactions. Alkanes, in contrast, do not have a functional group and are less reactive ...

Straightforward skeletal editing chemistry now enables the direct insertion of nitrogen into carbon–carbon double bonds.

The hydroalkylation of alkenes with alkyl halides was applicable to a wide range of substrates and features excellent functional group compatibility. Moreover, the catalytic system enabled ...

The longest unbranched chain containing the functional group is the parent molecule, or simply the longest unbranched chain for alkanes. Remember that, the longest chain can go round a bend.
