Functional groups

Identify the functional groups (e.g. alcohol, alkene, etc ) in the following molecules:

1.26) CH3COCH2CH3

The functional group is Ketone:

  • Ketones have 3 or more carbons in a carbon chain
  • the condensed structural formula consists of a CO found in the middle of the chain as you can see here:

CH3COCH2CH3

  • there are four carbons in this chain making the prefix buta-
  • the alkane name is butane
  • because this is ketone I will drop the -e and add ~one
  • the name will be Butanone
