Identify the wrong statement/s
I) All halogens are coloured
II) F₂ and Cl₂ are gases whereas Br₂ and I₂ are liquids
III) I₂ is sparingly soluble in water but is soluble
in various organic solvents like CCl₄, CS₂ etc.

I) All halogens are coloured
II) F₂ and Cl₂ are gases whereas Br₂ and I₂ are liquids
III)  Solubility follows law of "like" dissolves "like". Therefore, a non-polar molecule stays insoluble in polar solvent and solubilises into a non-polar solvent and vice-versa. Since I₂​ is non-polar and H2​O is polar, therefore they are immiscible.  but is soluble in various organic solvents like CCl₄, CS₂ etc.
