Amongst the following compounds, identify which are insoluble, partially soluble and highly soluble in water
(ii) toluene

Explanation

### Step-by-Step Solution:

1. **Identify the Compound**: The compound we are analyzing is toluene, which has the chemical formula C₇H₈.

2. **Determine the Polarity of Toluene**: Toluene consists of a benzene ring (C₆H₅) with a methyl group (CH₃) attached. The structure of toluene indicates that it is a non-polar molecule due to the symmetrical distribution of charge and the presence of carbon and hydrogen atoms, which have similar electronegativities.

3. **Understand the Nature of Water**: Water (H₂O) is a polar solvent. This polarity arises from the difference in electronegativity between oxygen and hydrogen atoms, leading to a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atoms.
