sodium chloride is an ionic compound whereas hydrogen chloride is a gas because
a)sodium is reactive
b)covalent bond is weaker than ionic bond
c)hydrogen chloride is a gas
d)covalent bond is stronger than ionic bond
Answers
In HCl we have covalent bond while in NaCl we have ionic bond.
Thus, NaCl is solid and HCl is gaseous.
Answer: Option (b) is the correct answer.
Explanation:
When there is transfer of electrons from one atom to another then it results in the formation of ionic bond. Whereas when there is sharing of electrons from one atom to another then it results in the formation of covalent bond.
Sodium chloride is an ionic compound as Na and Cl are linked by an ionic bond. So, in ionic compounds strong force of attraction exists because the respective atoms have opposite charges.
Whereas hydrogen chloride is a covalent compound as there is sharing of electrons between H and Cl. So, there is less force of attraction between covalent compounds.
Thus, we can conclude that sodium chloride is an ionic compound whereas hydrogen chloride is a gas because covalent bond is weaker than ionic bond.
