1.	Arrange the following in the increasing order of Basicity?KOH ,,,Rb(OH).please tell me the reason
Answer» <STRONG>Answer: RbOH > KOH > Mg(OH)2 > AL(OH)3 Explanation: Generally basicity of oxides / hydroxides decreases from left to right along a period. In the the 3rd period, we see that Na20 is a strong base, MGO is basic and Al203 is amphoteric. So it can be said that hydroxides of G-1 are more basic than hydroxides of G-2. Again if we MOVE from top to bottom along G-1, radius of cation increases, ionisation enthalpy decreases ( less energy is required to lose electron). As a result solubility and basicity increases down the group.
