What is the name of the functional group that is attached to this hydrocarbon? The first and last of a chain of three carbons are each single bonded to 3 H; the center carbon is double bonded to O. alkyl halide alcohol carbonyl ketone

Ketone

Explanation:

According to the description of the functional group attached to the hydrocarbon - the first and last of a chain of three carbons are each single bonded to 3 hydrogen (H)atoms; the center carbon is double bonded to an oxygen atom, O - it can be deduced that the functional group is a ketone group.

A ketone is a functional group with the structure R₂-C=O, where the two R are  alkyl or phenyl groups which may be the same or different. The carbon in a double covalent bond with oxygen is called the carbonyl carbon. The two R groups are bonded to the carbonyl carbon in single covalent bonds.

In the hydrocarbon in this question, the two R groups are methyl groups, CH₃ bonded to the carbonyl carbon. The name of the hydrocarbon is propanone and it is a ketone molecule.
