Question

which one has highest melting point
(b) mgcl2 (a) nacl
(c) alcl3 (d) kcl​

Answer 1

Answer:

b)mgcl2

Explanation:

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. ... So the melting point of NaCl is much higher than that of AlCl3.

Answer 2

Answer:

c) alcl3 is the correct answer. alcl3 has the highest melting point
