$\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{3}$
$\mathrm{C}_{6} \mathrm{H}_{6}$
$\mathrm{H}_{2} \mathrm{O}$
$\mathrm{CH}_{3} \mathrm{SH}_{3}$

Accepted Answer

∻Solution∻ ‖ 1 ⋮ **Identify the substances**: The question provides four different chemical substances: butane $\mathrm{C_4H_{10}}$, benzene $\mathrm{C_6H_6}$, water $\mathrm{H_2O}$, and methanethiol $\mathrm{CH_3SH}$. ‖ ‖ 2 ⋮ **Understand surface tension**: Surface tension is a physical property that arises from the intermolecular forces between the molecules at the surface of a liquid. The stronger the intermolecular forces, the higher the surface tension. ‖ ‖ 3 ⋮ **Analyze intermolecular forces**: Water has strong hydrogen bonding, benzene has π-π interactions, butane has van der Waals forces, and methanethiol has weak hydrogen bonding and van der Waals forces. ‖ ‖ 4 ⋮ **Compare surface tension**: Substances with stronger intermolecular forces (like hydrogen bonds in water) have higher surface tension compared to those with weaker forces (like van der Waals forces in butane). ‖ ‖ 5 ⋮ **Determine the substance with the lowest surface tension**: Among the given substances, butane has the weakest intermolecular forces and thus the lowest surface tension. ‖ ∻Answer∻ ⚹ Butane $\mathrm{C_4H_{10}}$ has the lowest surface tension. ⚹ ∻Key Concept∻ ⚹ Surface tension is influenced by intermolecular forces. ⚹ ∻Explanation∻ ⚹ Butane has the weakest intermolecular forces among the given substances, leading to the lowest surface tension. ⚹◊Which substance would exhibit the highest intermolecular forces among the options provided?⍭ Generate me a similar question◊
