Answer :
To determine whether a molecule is an unsaturated fatty acid, we need to look for the presence of one or more double bonds between carbon atoms. Unsaturated fatty acids are characterized by these double bonds, which differentiate them from saturated fatty acids that have only single bonds between carbon atoms.
Given the molecular fragments, we should check each fragment for double bonds. Here’s the analysis of the provided fragments:
1. Fragment CH₂
- This represents a methylene group, which has single bonds only.
2. Fragment A
- Information about "A" is not provided explicitly, so we cannot determine its structure. We would typically need more context to identify this fragment.
3. Fragment CH2
- This represents another methylene group, indicating single bonds only.
4. Fragment CH₂
- Again, this is a methylene group with single bonds.
5. Fragment CH₂
- Another methylene group with single bonds.
6. Fragment NH₂
- This indicates an amine group, which does not include carbon-carbon bonds and therefore, does not contribute to the detection of saturated or unsaturated status.
7. Fragment D
- Similarly to "A", we lack explicit information on "D".
8. Fragment H
- This is a single hydrogen atom and does not help in determining saturation levels of the fatty acid.
Given the fragments provided, none of the fragments explicitly indicate the presence of a double bond. Therefore, more information would typically be needed to conclusively identify an unsaturated fatty acid from these fragments alone. In this case, there is not enough evidence to show the presence of an unsaturated fatty acid.
