( HCl ) gas is covalent and ( NaCl ) is an ionic compound. This is because

Options

  1. ASodium is highly electropositive
  2. BHydrogen is a non-metal.
  3. C( HCl ) is a gas.
  4. DElectronegativity difference between ( H ) and ( Cl ) is less than ( 2.1 ).

Correct answer

D. Electronegativity difference between ( H ) and ( Cl ) is less than ( 2.1 ).

Step-by-step solution

The electronegative difference between ( H ) and ( Cl ) is less than ( 2.1 ), therefore, ( HCl ) gas is covalent compound.
