Which of of the following organic substances is most readily soluble in water benzend pyridine octane carbon tetrachloride toluene?

Answer 1

Among the substances listed, pyridine is the most readily soluble in water. This is due to its polar nature and the presence of a nitrogen atom that can form hydrogen bonds with water molecules. In contrast, benzene, octane, carbon tetrachloride, and toluene are largely nonpolar and exhibit low solubility in water.
