Question

In polar covalent bonds, electrons are shared unequally between two atoms and results in partial charges in both atoms?

1) True
2) False

Answer 1

True, polar covalent bonds involve unequal sharing of electrons between two atoms, leading to partial charges.

Step-by-step explanation:

The statement is true. In a polar covalent bond, electrons are indeed shared unequally between two atoms. This unequal sharing results in one atom having a slightly negative charge and the other a slightly positive charge, often denoted as δ- and δ+ respectively. These partial charges occur because the atoms have different electronegativities, causing the electrons to be more attracted to one nucleus over the other.
