Question

For which of the following van't Hoff factor cannot be greater than unity? (A) K4[. Fe (. CN .)6 ]. (B) AlCl3 (C) H2NCONH2 (D) KNO3

For urea the van't Hoff factor can not be greater than unity because urea is non-ionisable (non-electrolyte) while others are ionic compounds so will undergo dissociation in aqueous solution so, van't Hoff factor will become more than unity.
