A) \[CaC{{l}_{2}}.2{{C}_{2}}{{H}_{5}}OH\]
B) \[2CaC{{l}_{2}}.3{{C}_{2}}{{H}_{5}}OH\]
C) \[CaC{{l}_{2}}.4{{C}_{2}}{{H}_{5}}OH\]
D) \[CaC{{l}_{2}}.{{C}_{2}}{{H}_{5}}OH\]
Correct Answer: C
Solution :
Ethanol forms a solid derivative with metallic salt in which alcohol molecule shows solvation phenomena, e.g., \[\text{CaC}{{\text{l}}_{\text{2}}}\text{.4}{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{OH}\text{.}\]That is why alcohols cannot be dried by anhydrous \[\text{CaC}{{\text{l}}_{2}}.\]
