Among the following compounds, identify which are insoluble, partially soluble, and highly soluble in water ?
`a.` Phenol `b.` Toluene
`c.` Formic acid `d.` Ethylene glycol
`e.` CHMloroform `f.` Pentanol

Explanation

Phenol `(C_(6)H_(5)OH)`: Is partiallty soluble in water due to weak dipole-dipole interactions in the molecules of pheneol and water. Infact, phenyl `(C_(6)H_(15))` group is of non-polar nature.
toluene `(C_(7)H_(18))`: Is insoluble in water because it is an aromatic hydrocarbon (non-polar) while water is polar in nature.
Formic acid (CHOOH): Is highly soluble in water since iut can form hyderogen bending with water.
ethylene glycol `(HOCH_(2)CH_(2)OH)` : Is highly soluble (or miscible) in water since it can form hydrogen bonding with water.
chloroform `(CHCI_(3))` : Is insolube (or immiscible in water because it is a heavy organic liquid and forms a separate layer.
Pentanol `(C_(5)H_(11)OH)` In partially soluble in water because the bulky `C_(5)H_(11)` ground decreases its extent of hydrogen bonding with water.
