Problem 84 - Chemistry The Central Science

Question

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

Step-by-Step Solution

Answer

An "ene-one" molecule must contain both an alkene functional group (-C=C-) and a ketone functional group (-C(=O)-) as part of its structure.

Step 1: Understand what "ene-one" means

To identify the functional groups in an "ene-one" molecule, we need to understand the meaning of "ene" and "one." The term "ene" typically refers to an alkene, which consists of a carbon-carbon double bond. On the other hand, "one" refers to a ketone, which contains a carbonyl group connected to two other carbons.

Step 2: Identify the functional groups for alkenes

In an alkene, the carbon-carbon double bond is the main functional group present. An alkene functional group has the general formula -C=C-.

Step 3: Identify the functional groups for ketones

In a ketone, the main functional group is a carbonyl group, which consists of a carbon double-bonded to an oxygen atom. The general formula for a ketone functional group is -C(=O)-, where the carbonyl carbon atom is connected to two other carbon atoms.

Step 4: Combine the functional groups for "ene-one" molecules

Now that we know the functional groups for both alkenes and ketones, we can combine them to identify the functional groups required for an "ene-one" molecule. An "ene-one" molecule must have both an alkene functional group (-C=C-) and a ketone functional group (-C(=O)-) as part of its structure. In conclusion, a molecule labeled as an "ene-one" must contain both an alkene functional group (-C=C-) and a ketone functional group (-C(=O)-).
