Which has the highest surface tension at a given temperature?

Question

Quizplus · Accepted Answer

The surface tension of a liquid depends on the cohesive forces between its molecules. The higher the cohesive forces, the higher the surface tension. Looking at the given options, we can see that all the molecules have the same chemical formula (C4H10O). Therefore, we can assume that the only difference in their properties is the arrangement of molecules or the isomerism. In the case of option D, the molecule has a cyclohexane ring, which makes the molecule more compact and enhances the cohesive forces between the molecules. Hence, the surface tension of option D is expected to be the highest among the given options.
