Question

how do the melting points of ionic compounds compare to water?
a very low
b slightly above room temperature
c very high
d same

Explanation:

Ionic compounds have strong electrostatic forces between ions, requiring high energy to break, so their melting points are very high. Water (a molecular compound with hydrogen bonding) has a much lower melting point (0°C) compared to typical ionic compounds (e.g., NaCl melts at 801°C). Option a is wrong (ionic mp is high), b is wrong (not slightly above room temp), d is wrong (mp differs). So c is correct.

Answer:

c. very high
