Determine if the following pairof molecules is isomers or conformers?
A
Conformers
B
Isomers
C
None of them
Verified step by step guidance1
Identify the molecular formula of each molecule. Both molecules have the same number of carbon and hydrogen atoms, indicating they could be isomers or conformers.
Examine the connectivity of the atoms in each molecule. Isomers have different connectivity, while conformers have the same connectivity but differ in spatial orientation.
Observe the presence of any double bonds or rings. The first molecule is a linear chain with double bonds, while the second molecule is a cyclic structure with double bonds.
Determine if the molecules can be interconverted by rotation around single bonds. Conformers can be interconverted by such rotations, while isomers cannot.
Conclude that since the molecules have different connectivity (one is linear and the other is cyclic), they are not conformers but rather structural isomers.
