Answer
The theoretical Van't Hoff factor i for C12H22O11 is 1
Step-by-step explanation
The Van't Hoff factor, i, is the number of particles formed in a solution from one formula unit of solute.
The Van't Hoff factor, i, is a property of the solute. In an ideal solution, i does not depend on the concentration of the solution.
For a nonelectrolyte, like (C12H22O11), which does not separate into ions in solution, Van''t Hoff factor, i = 1 because 1 molecule of sucrose (C12H22O11) forms only one particle in solution.f
