Question
100%
Determine the name of the following structure
**Description:**
The chemical structure depicted consists of a four-carbon chain with a double bond between the second and third carbon atoms and a substituent (an aldehyde group, -CHO) attached to the first carbon of the longer chain. Additionally, there is a methyl group (-CH₃) attached to the second carbon of the chain.
### Detailed Analysis:
1. **Carbon Chain Identification:**
- The longest continuous carbon chain in the structure has four carbon atoms, which indicates that the base name will be derived from "butane."
2. **Double Bond Location:**
- The presence of a double bond between the second and third carbons indicates that it is an alkene, resulting in the name "but-2-ene."
3. **Substituent Group Identification:**
- An aldehyde group (-CHO) is attached to the first carbon of the main chain, changing the suffix to "-al," forming "but-2-enal."
4. **Methyl Group Identification:**
- A methyl group (-CH₃) is attached to the second carbon of the main chain.
### Naming the Structure:
Combining all the parts and identifying the position correctly, the systematic name of the compound is **3-methylbut-2-enal**.
**Final Name:**
**3-Methylbut-2-enal**
By breaking down and analyzing each part of the structure, we can accurately determine its IUPAC name.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe1bd5724-e7b1-4097-b4b3-5c856c93a5be%2F348d0489-b74c-4da4-aa03-ecf73465391b%2Fiq2wnme_processed.jpeg&w=3840&q=75)
