$CaCl_2 \cdot 4C_2H_5OH$

Vedclass · Answer

(A) Step $1$: Anhydrous $CaCl_2$ acts as a drying agent by absorbing water to form hydrates like $CaCl_2 \cdot 6H_2O$.Step $2$: When used with alcohols like ethanol, $CaCl_2$ reacts to form a stable solvated adduct instead of merely acting as a desiccant.Step $3$: The chemical reaction is $CaCl_2 + 4C_2H_5OH \rightarrow CaCl_2 \cdot 4C_2H_5OH$.Step $4$: Therefore, the correct stoichiometry of the adduct formed is $CaCl_2 \cdot 4C_2H_5OH$.

Ethanol cannot be dried using anhydrous $CaCl_2$ because it forms a stable solvated adduct. Which of the following represents the correct stoichiometry of the adduct formed?
