A

Both LiCl and `MgCl_2` 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

Text Solution

Verified by Experts

The correct Answer is:
A,B,C
(A)`Li^+ and Mg^(2+)` 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)Li is the most covalent due to smaller cation and bigger anion. (According to Fajan's rule)
