Explain the following: a. Which of the following Na, Mg, Si and P would have the greatest difference between the IE_(1) and IE_(2) ? Explain? b. The EN's of B, Al and Ga are 2.0, 1.5 and 1.6 respectively. The trends is not regular.Explain? c. Li_(2)CO_(3) decomposes on heating but other alkali metal barbonate ( e.g. Na_(2)CO_(3) ) does not. Explain? d. Expalin why Cu^(o+) is found only is solid state and not solutions. e. Be of N have extremely low value of EA (i.e. less negative value)against the trend. Explain? f. Arrange the following in decreasing order of their properties indicated: Na^(o+)Mg^(2+) and Al^(3+) i. Ionic mobillity in H_(2)O ii. Size of ions iii. Standard reduction protential (E_(M^(x+(aq.)))^(ɵ)//M_(s)) iv. Extent of hydration v. Hydration energy vi. Size of hydrated ions g. In iodomentry. why KI is not added dropwise to an acidified solution of KMnO_(4) but reverse is done? h. Why the decrease in size between Li and Be is much greater than that between Na and Mg or K and Ca ? i. K_(2)CO_(3) is less soluble than Cs_(2)CO_(3) or Rb_(2)CO_(3) while among group 2 elements MgCO_(3) is more soluble than BaCO_(3) . j. Expalin the decreasing order of solubility of sulphate of group 2 elements. k. 'EA' of Cl is the highest among the halogens, yet F is the strongest oxidising agent'. Why?
