Chapter 21, Problem 144CWP

Interpretation Introduction

Interpretation: The given organic compounds are arranged according to their increasing water solubility.

Concept introduction: Hydrocarbons are non-polar in nature, whereas water is polar. The saturated hydrocarbons are not more soluble in water and their solubility decreases on increasing the polar hydrocarbon chain. On the other hand unsaturated and aromatic hydrocarbons show slightly solubility in water. The solubility of hydrocarbons depends on intermolecular forces such as hydrogen bonding, ionic forces and dipole-dipole interactions. The given organic compounds are butanoic acid (A), $\text{2-methyl-pent-2-ene}$ (B) and $\text{pentan-2-one}$ (C).

To determine: Increasing order of water solubility of the given organic compounds.
