B. Unequally
Explicación
## Step 1In a polar covalent molecule, the electrons are not shared equally. This is because the atoms in the molecule have different electronegativities. ## Step 2Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The atom with the higher electronegativity will pull the electrons closer to itself, creating a partial negative charge.## Step 3Conversely, the atom with the lower electronegativity will have a partial positive charge because the electrons are being pulled away from it.## Step 4This unequal sharing of electrons creates a dipole moment in the molecule, which is the characteristic feature of a polar covalent molecule.
