Question

2 in a water (h₂o) molecule, the bond between oxygen and each hydrogen is an example of
nonpolar covalent bond.
polar covalent bond.
ionic bond metallic bond.
metallic bond.
clear all

Explanation:

In a water molecule (\(H_2O\)), the bond between oxygen and hydrogen involves sharing electrons, but oxygen is more electronegative than hydrogen. This causes an unequal sharing of electrons, creating a dipole (partial positive on H, partial negative on O). Nonpolar covalent bonds have equal electron sharing (e.g., \(O_2\)). Ionic bonds involve electron transfer (not sharing), and metallic bonds are in metals. So the O - H bond in \(H_2O\) is a polar covalent bond.

Answer:

B. Polar covalent bond.
