Arrange the following compounds in order of increasing strength of intermolecular forces: CH₃CH_3,CH₃CH₂CH₃, CH₄

Question

Quizplus · Accepted Answer

The strength of intermolecular forces mainly depends on factors like molecular size, shape, polarity, and the presence of functional groups. 
Looking at the given compounds, CHS1U1B14 has the strongest intermolecular forces due to the presence of a larger and more polarizable sulfonate group. 
Among the remaining compounds, CHS1U1B13S1U1B0CHS1U1B13 will have stronger intermolecular forces because it has two sulfonate groups and is anionic in nature. 
S1U1B1 S1U1B0 and CHS1U1B14S1U1B0S1U1B1 will have weaker intermolecular forces as they are neutral compounds and have small molecular sizes. 
Based on this, the correct order is CHS1U1B14 < CHS1U1B13S1U1B0CHS1U1B13 < CHS1U1B13S1U1B0CHS1U1B12S1U1B0CHS1U1B13S1U1B0 < S1U1B1 S1U1B0 < CHS1U1B14S1U1B0S1U1B1. 
Therefore, option D is the correct answer.
