Question

correct order of melting points NaCl,KCl,AlCl3​

Answer 1

Answer:

We know that ionic compounds have more melting and boiling points than covalent compounds

Comparing NaCl and AlCl3

NaCl is more ionic than AlCl3

because ionic character depends on the size of cations. As here anions are same, more the size of cation, more the ionic character. Na +

has more size than Al 3+. So the melting point of NaCl is much higher than that of AlCl 3

Answer 2

NaCl> KCl> AlCl3..................
