Doubt by Aaliya
Pls give melting point order in NaCl,KCl,RbCl,CsCl .. shouldnt it be CsCl>RbCl>KCl>NaCl
As melting point is inversely propertional to polarization power ..
Answers
Answer by Dr. Rakhee
Smaller the cation greater is its polarizing power and hence larger is the covalent character. The covalent character decreases as size of cation increases.
NaCl > KCl > RbCl > CsC
