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
(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.
