Hydrogen, Alkali and Alkaline earth metals


Lithium atom and ion are very small and are comparable in sizes to those of Mg. Their polarizing power (charge / radius) are almost the same, and as a result have similar properties. 


        LiNO3 on heating gives


        (A)    LiNO2 and O2


        (B)    Li2O, NO2 and O2


        (C)    Li + NO2 + O2


        (D)    does not decompose on heating 


 


        The statements that are true of LiOH are


        (i)     it is a strong base


        (ii)    it decomposes on heating to give the oxide


        (iii)    it is a work base


        (iv)   it is the least soluble of alkali metal hydroxides


 


(A)        (i), (ii)


(B)        (iii), (iv)


(C)        (i), (iii), (iv)


(D)        (ii), (iii), (iv) 


 


        The fluorides of alkali metals having the highest and lowest solubility are, respectively


        (A)    LiF, CsF


        (B)    NaF, CsF


        (C)    CsF, LiF


        (D)    CsF, NaF
