323073 \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\) cannot be dried by anhydrous \(\mathrm{CaCl}_{2}\), because

1 \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\) is soluble in water
2 Explosion takes place
3 \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\) forms adduct with \(\mathrm{CaCl}_{2}\)
4 None of these
