Question

why LiCl has higher
Boiling point then HCl
​

Answer 1

Answer:

LiCl has higher boiling point that HCl because of the stronger intermolecular forces in LiCl.

Explanation:

A substance which has lower a boiling point would have weaker inter molecular force. Here HCl has dipole dipole interaction between its atoms. Which is weaker than ionic interaction between LiCl . Dipole dipole interaction is the result of attraction between the positive end of one polar molecule and the negative end of another polar molecule. On the other hand, in LiCl, Li⁺ is very small in size and Cl⁻ is larger and hence they have an ionic bond hence stronger inter molecular forces and hence LiCl has a higher boiling point.

Answer 2

Because of strong interionic forces in LiCL than HCl.

Explanation:

• Lithium chloride, LiCl and Hydrogen chloride, HCl both are ionic compounds .
• Lithium chloride has higher boiling point than hydrogen chloride because the ionic bond formed between the lithium ion and chloride ion in Lithium chloride is stronger as compared to the ionic bond formed between the hydrogen ion and chloride ion.
• Lithium ion is very small and Chloride ion is large in size and it is sufficient condition for strong ionic bond.
• Due to this reason , Licl has higher boiling point than HCl
