Question: Least melting point is shown by the compound :...
Least melting point is shown by the compound :
A
PbCl2
B
SnCl4
C
NaCl
D
AlCl3
Answer
SnCl4
Explanation
Solution
Sn4+ has highest polarising power amongst Na+, Pb2+ , Sn4+ and Al3+ because of smaller size and higher charge. So SnCl4 is most covalent and thus has least melting point.
