Question

Which of the following is NOT true about ionic compounds?

Answer 1

Answer:

C.it has a lower melting temperature

Explanation:

A good way to solve this problem may be to think about a simple ionic compound, such as salt, NaCl:

• NaCl easily disolves in water, so options A and B are true about ionic compounds.

• Salt powder does not conduct electricity, however a concentrated solution of salt in water does. Meaning that option D is true as well.

• NaCl has a melting point of 801 °C, not particularly a low value. Thus the correct option is C.
