Determine if the following pairof molecules is isomers or conformers?

• A. Conformers
• B. Isomers
• C. None of them

Answer: (A)

Verified step by step guidance

1. Examine the molecular structures provided in the image. The first molecule is an aldehyde with a carbonyl group (C=O) at the end of a carbon chain, and the second molecule is also an aldehyde with a similar carbonyl group.
2. Identify the functional groups present in each molecule. Both molecules contain an aldehyde group, which is characterized by the presence of a carbonyl group bonded to a hydrogen atom.
3. Count the number of carbon atoms in each molecule. Both molecules have the same number of carbon atoms, indicating they have the same molecular formula.
4. Consider the connectivity of the atoms in each molecule. Isomers have the same molecular formula but different connectivity of atoms, while conformers are different spatial arrangements of the same molecule.
5. Determine if the molecules are isomers or conformers. Since both molecules have the same connectivity and differ only in the spatial arrangement, they are conformers.
