Question

the melting point of NaCl is
a.1074k
b.1047k
c.100k
d.1000k​

Answer 1

Answer:

(a) 1047k

or you can also convert it into celcius,

we get,

801°C

Answer 2

Explanation:

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

Comparing NaCl and AlCl

3

. NaCl is more ionic than AlCl

3

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

And it is A 1074k.
