melting points

[AMahadi]

Why does NaCl have a higher melting point than HCl?

[Zaynab Hashm 2I]

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.

[Lauren Tanaka 1A]

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.

[Shrayes Raman]

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

[Jainam Shah 4I]

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.

[Ashley Nguyen 2L]

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.
