**Understanding Surface Tension in Liquids****Question 12.4:***Choose the substance with the lowest surface tension in the liquid phase.*The options provided are:- (CH₃)₂CO (Acetone)- H₂O (Water)- CH₃SH (Methanethiol)- CH₃CH₂CH₂CH₃ (Butane)When evaluating surface tension, it’s important to understand that surface tension is a measure of the cohesive forces at the surface of a liquid. Typically, substances with stronger intermolecular forces exhibit higher surface tension. In this scenario:- **Water (H₂O)** has very high surface tension due to strong hydrogen bonding between its molecules.- **Acetone ((CH₃)₂CO)** and **Methanethiol (CH₃SH)** have lower surface tension compared to water. Methanethiol has weaker hydrogen bonding due to the presence of a sulfur atom which is less electronegative than oxygen.- **Butane (CH₃CH₂CH₂CH₃)**, being a non-polar molecule with only dispersion forces, has the lowest surface tension among the given options.Therefore, the substance with the lowest surface tension in the liquid phase is **CH₃CH₂CH₂CH₃ (Butane)**.

Concept explainers

States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
