Question
Which of the following statement (s) is/are true ?
Options
A.Both LiCl and MgCl2 are deliquescent.
B.Lithium is least reactive but the strongest reducing agent amongst all the alkali metals.
C.Liquid sodium metal is used as a coolant in fast breeder nuclear reactors.
D.Lithium iodide is the most ionic in nature among alkali metal halides.
Solution
(A) Li+ and Mg2+ have higher polarising power and thus attract more number of water molecules.
(B) Li is least reactive because of its highest ionisation energy on account of smaller size.
(C) It is one of the uses of liquid sodium. It has low melting point.
(D) LiI is the most covalent due to smaller cation and bigger anion. (According to Fajan′s rule)
