When converting from common names to IUPAC names:
- Ethylene is an alkene, so its IUPAC name is "Ethene."
- Acetylene is an alkyne, so its IUPAC name is "Ethyne."
- Acetic acid is a carboxylic acid, so its IUPAC name is "Ethanoic acid."
- Methyl alcohol is a simple alcohol, so its IUPAC name is "Methanol."
- Acetone is a ketone, and its IUPAC name is "Propane-2-one."
1. Ethylene: The IUPAC name of Ethylene (\(\text{CH}_2 = \text{CH}_2\)) is Ethene. It is an alkene with two carbon atoms and a double bond between them.
2. Acetylene: The IUPAC name of Acetylene (\(\text{CH}_\text{≡}\text{CH}\)) is Ethyne. It is an alkyne with a triple bond between two carbon atoms.
3. Acetic acid: The IUPAC name of Acetic acid (\(\text{CH}_3 - \text{COOH}\)) is Ethanoic acid. It is a carboxylic acid with two carbon atoms.
4. Methyl alcohol: The IUPAC name of Methyl alcohol (\(\text{CH}_3 - \text{OH}\)) is Methanol. It is the simplest alcohol, with one carbon atom and a hydroxyl group (-OH).
5. Acetone: The IUPAC name of Acetone (\(\text{CH}_3 - \text{CO} - \text{CH}_3\)) is Propane-2-one. It is a ketone with three carbon atoms and a carbonyl group (C=O) attached to the second carbon.
