Answer:
i = 1
Explanation:
Van't Hoff factor (i) is explained as the number of ions dissolved in solution.
It is needed to determine colligative properties which depend on the amount of solute.
C₇H₇NO is an organic compound → benzamide
All the organic compound have 1, as Van't Hoff factor.
In order to predict i, you consider ionic salts. For example:
AlCl₃
CaCl₂
NH₄NO₃
When you dissociate them, you determine i:
AlCl₃ → Al³⁺ + 3Cl⁻ i =4
CaCl₂ → Ca²⁺ + 2Cl⁻ i = 3
NH₄NO₃ → NH₄⁺ + NO₃⁻ i =2
