Question

If a molecule is an "ene-one," what functional groups must it have?

Short answer

An "ene-one" molecule must contain two functional groups: 1. An alkene functional group, represented by a carbon-carbon double bond (C=C), and 2. A ketone functional group, represented by a carbonyl group (C=O) bonded to two other carbon atoms (RC(=O)R').

Step-by-step solution

Identifying the term "ene" in "ene-one"

The term "ene" in organic chemistry usually refers to the presence of a carbon-carbon double bond, which is an alkene functional group. Alkenes have the general formula CnH2n, where n is the number of carbon atoms.

Identifying the term "one" in "ene-one"

The term "one" in organic chemistry is often related to the presence of a carbonyl group (C=O), specifically in ketones. Ketones are organic compounds with the carbonyl group bonded to two other carbon atoms, having a general formula of RC(=O)R', where R and R' can be any alkyl or aryl group.

Combining the terms "ene" and "one" to form functional groups

Now that we have identified the individual functional group meanings of "ene" and "one," we can combine them to form the functional groups that must be present in an "ene-one" molecule. In this case, an "ene-one" molecule must contain: 1. An alkene functional group: A carbon-carbon double bond (C=C) 2. A ketone functional group: A carbonyl group (C=O) bonded to two other carbon atoms (RC(=O)R') These two functional groups must be present in the molecule for it to be classified as an "ene-one."
