Solubility of an ionic compound in water is mainly dependent on: a.Lattice enthalpy , b. Hydration enthalpy Both these factors oppose each other and the resultant of these determines the solubility of an ionic compound in water. If lattice enthalpy has greater value, the compound is less soluble. In case hydration enthalpy has greater value, the compound is highly soluble in water. Compound of alkaline earth metals are less soluble than alkali metals, due to:

(a) Explain any two physical properties of ionic compounds giving reason. (b) List any two metals found in free state in earth's crust. Where are they located in activity series ? (c) Metals towards the top of the activity series can not be obtained from their compounds by reducing with carbon. Why?

The small size and high charge of Al^(3+) ion gives it a high charge density which is responsible for its tendency to show (a) covalency in its compounds in the gaseous state (b) high hydration energy which stabilizes its compounds in solution, and (c) high lattice energy of its compounds in the solid state. Thus aluminium can forms both covalent and ionic bond. Like halides of boron, halides of aluminium do not show back bonding because of increase in size of aluminium. Actually aluminium atoms complete their octets by forming dimers. Thus chloride and bromide of aluminium exist as dimers, both in the vapour state and in polar-solvents like benzene while the corresponding boron halides exists as monomer. In boron trihalides the extent of back bonding decreases with increases with increase in size of halogens and thus lewis acid character increases. All BX_(3) are hydrolysed by water but BF_(3) shows a different behaviour. Which of the following statements about anhydrous aluminium chloride is correct ?
