Which of the following pair of isomers are correctly matched with their relationship
A
Geometrical isomers.
B
Position isomers.
C
Functional group isomers.
D
Chain isomers.
Answer
Position isomers.
Explanation
Solution
The third pair of structures from the left shows two cyclic ethers with the same molecular formula but differing in the position of the double bond. This indicates they are position isomers. The other pairs are incorrectly matched: the first pair are not isomers, the second pair have different molecular formulas, and the fourth pair appear to be identical structures, not geometrical isomers.
