Chemistry - Complete P-block Question with Solution | TestHub

White phosphorus is non-polar and exists as P₄ molecules, so it is insoluble in water but soluble in non-polar solvents like CS₂, hence (A) is correct. Red phosphorus is polymeric in nature, so it is insoluble in both water and CS₂, making (B) incorrect. White phosphorus shows chemiluminescence (slow oxidation in air), so it glows in the dark, hence (C) is correct. Red phosphorus does not show this property, so (D) is incorrect.
