Potassium chloride is an ionic compound. The bond holding the atoms together is known as ionic bond. Strictly speaking it is NOT a discrete molecule of K + Cl- but a crystal lattice consisting of each K+ surrounded by Cl- ions and vice versa. The bonds in this lattice all have to be broken to melt the compound.
There is a strong electrostatic force of attraction between the chloride ions and the potassium ions. A large amount of heat energy has to be applied to break the strong bond holding the atoms, resulting in the compound having a high melting point.

Why does potassium chloride have such a high melting point?
Potassium chloride is an ionic compound. The bond holding the atoms together is known as a ionic bond. The bonds in this lattice all have to be broken to melt the compound.
Does sodium chloride have a high or low boiling point?
Iodine, at p=p0,Boiling point 457.4 K,  184.3 °C(So I don't know if you'd call this high or low? compared with what?)However the difference with melting point of Iodine (386.85 K,  113.7 °C) is remarkably small (< 71oC) and the solid is quite vaporous far below its boiling point (Triple point 386.65K (113.5oC), 12.07 kPa, just below melting point).
Why copper(ii)chloride has a high melting point than ethane?
Because it is a non metal and does not conduct electricity
