Question
What will be the value of Van’t Hoff factor (i) of benzoic acid if it dimerises in aqueous solution? How will the experimental molecular weight vary as compared to the normal molecular weight?
Short Note
Solution
`i = 1/2`
i = 0.5
The experimental molecular weight will be almost double the normal molecular weight.
