Sodium chloride is an ionic compound, whereas hydrogen chloride is mainly covalent because
Options
- ASodium is less reactive
- BHydrogen is non - metal
- CHydrogen chloride is a gas
- DElectronegativity difference in the case of hydrogen and chlorine is less than 2.1
Correct answer
B. Hydrogen is non - metal
Step-by-step solution
Hydrogen is non metal and non metal atoms form covalent bond The nature of a bond formed between two elements mainly depends on the difference of electronegativity. If difference of electronegativity of two atoms is more than 1.90, they from an ionic bond. And when this difference is less than 1.9, they form a covalent bond.
