Which type of bond is present in a molecule of hydrogen chloride, given electronegativities of H = 2.2 and Cl = 3.2?
Answer and explanation
Correct answer: A. A polar covalent bond
- Step 1: The electronegativity difference is 1.0.
- Step 2: The shared electrons are drawn towards chlorine, giving a polar covalent bond.
Answer
A polar covalent bond.
Why not the others: A non-polar covalent bond: the electronegativities differ. An ionic bond: the difference of 1.0 is too small for ionic bonding. A metallic bond: HCl contains no metal.
