For urea ( mathrmNH2 mathrmCONH2) the van't Hoff factor can not be greater than unity because urea is non-ionisable while other are ionic compounds so will undergo dissociate in aqueous solution so van't Hoff factor will become more then unity.

Q. For which of the following van't Hoff factor cannot be greater than unity?

$K_{4} [Fe (CN)_{6}]$

$AlCl_{3}$

$NH_{2} CONH_{2}$

$KNO_{3}$

For urea $(NH_{2} CONH_{2})$ the van't Hoff factor can not be greater than unity because urea is non-ionisable while other are ionic compounds so will undergo dissociate in aqueous solution so van't Hoff factor will become more then unity.
