Question

which of the following factors explains why h₂o is a polar molecule? the presence of two non - bonding pairs of electrons the presence of two bonding pairs of electrons an asymmetrical distribution of charge the presence of two hydrogen atoms

Explanation:

A polar molecule requires an asymmetric charge distribution. In H₂O, oxygen is more electronegative than hydrogen, creating partial charges. The bent molecular shape (from non-bonding electron pairs) prevents charge cancellation, leading to asymmetry. Non-bonding pairs, bonding pairs, or two H atoms alone don’t directly explain polarity—only asymmetric charge distribution does.

Answer:

an asymmetrical distribution of charge
