Why does NaCl have a higher melting point than HCl?

NaCl is an ionic bond, HCl is a covalent bond. Ionic bonds are stronger than coverlet bonds, and due to the higher attractions, they have a higher melting point.

NaCl will have a higher melting point than HCl since NaCl is an ionic bond and HCl is a covalent bond. Ionic bonds are generally stronger than a covalent bond so it takes more to break apart these bonds than those in covalent molecules.

NaCl has a ionic as opposed to a covalent bond which is stronger that HCl and there for melts at a higher temp

Ionic bonds always supersede Hydrogen Bonding in terms of strength of their attraction. That is why NaCl has a much higher melting point when compared to HCl.

NaCl's ionic bonding is much stronger than the covalent bonds holding HCl together. Because the bond is stronger, more energy is needed to break the bond, resulting in a higher melting point.
