Answer and explanation
Correct answer: A. H₂O
- Step 1: H2O is bent, so its bond dipoles do not cancel.
Answer
H₂O.
Why not the others: CO₂: its two polar bonds point in opposite directions and cancel. CH₄: the four identical bonds are arranged symmetrically. N₂: the two atoms are identical, so the bond is non-polar.
