Question
The correct sequence of increasing melting points of BeCl2, MgCl2, CaCl2, SrCl2 and BaCl2 is
Options
A.BeCl2 < SrCl2 < CaCl2 < MgCl2 < BaCl2
B.BeCl2 < MgCl2 < CaCl2 < SrCl2 < BaCl2
C.BeCl2 < CaCl2 < MgCl2 < SrCl2 < BaCl2
D.MgCl2 < BeCl2 < SrCl2 < CaCl2 < BaCl2
Solution
The ionic character and hence the m.pt. increases as the size of cation increases.
