![### Analysis of 4-Methyl-2-Pentanone (Methyl Isobutyl Ketone)
The diagram is a structural representation of an organic compound known as 4-methyl-2-pentanone, also commonly referred to as methyl isobutyl ketone (MIBK). Below is a detailed description based on the annotations provided:
1. **Methyl Group**:
- The first arrow (labeled "1") points to a methyl group (CH3) attached to the second carbon of the main carbon chain.
- This substituent is what makes the compound a methylated ketone.
2. **Ketone Functional Group**:
- The second arrow (labeled "2") points to the carbonyl group (C=O) present at the second carbon of the chain.
- This indicates that the compound is a ketone, denoted by the suffix "-one" in IUPAC nomenclature.
3. **Hydrogen Atom**:
- The third arrow (labeled "3") points to a hydrogen atom bonded to the carbon adjacent to the carbonyl group.
- This hydrogen is part of the methylene (CH2) group connected to the carbonyl carbon.
### Detailed Structure:
- The main carbon chain consists of five carbons.
- The carbonyl group is attached to the second carbon within this chain.
- A methyl group (CH3) is attached to the fourth carbon of the chain, identifying it as 4-methyl.
- The structural formula can also be written as CH3COCH2CH(CH3)2.
### Applications:
4-Methyl-2-pentanone is used industrially as a solvent for paints, varnishes, nitrocellulose, lacquers, and certain polymers and resins. It is also utilized in the production of rubber and pharmaceuticals.
By understanding the placement of these functional groups and substituents, one can gain insight into the chemical reactivity, physical properties, and applications of 4-methyl-2-pentanone.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F62f6355a-05e6-4234-9d59-a73a1309b418%2Fb8f0aef3-7248-4dd8-a8c1-bf7bd260ac77%2Fpxwnhs_processed.jpeg&w=3840&q=75)
