3. State the reason for the following: (10)(i) HI has more covalent character than HCl.(ii) Ionic compounds are more soluble in water than benzene.(iii) The radius of S2-ion is larger than the radius of Cl-ion.(iv) In NaBr crystal, each ion is octahedrally surrounded by ions of opposite charge.(v) In HF, the experimental bond length value is less than the sum of covalent radii.

HI is more covalent than HCl since covalent nature increases if the size of anion increases ( size of I is more than cl) Water is polar solvent where benzene is non polar ...ionic compounds are soluble in polar solvents as they r polar compounds ( like dissolve like)
