| (i) polarising powers of\[L{{i}^{+}}\]and\[M{{g}^{2+}}\]are almost same |
| (ii) like\[Li,\]\[Mg\]decomposes water very fast |
| (iii)\[LiCl\]and\[MgC{{l}^{2}}\]are deliquescent |
| (iv) like\[Li,Mg\]do not form solid bicarbonates |
A) (i) and (ii)
B) (ii) and (iii)
C) only (ii)
D) only (i)
E) (ii) and (iv)
Correct Answer: C
Solution :
Lithium and magnesium shows diagonal relationship. Some points of similarity are (I) polarizing power of\[L{{i}^{+}}\]and\[M{{g}^{+}}\]are almost same (II) like\[Li,Mg\]decomposes water very slowly. (III)\[LiCl\]and\[MgC{{l}_{2}}\]are deliquescent. (IV) Like\[Li,Mg\]do not form solid bicarbonates.
