Which of the following molecules is polar?

Question

Quizplus · Accepted Answer

CH₂Cl₂ is a polar molecule because it contains polar bonds (between carbon and chlorine atoms), and those polar bonds do not cancel each other out due to the tetrahedral arrangement of atoms around the central carbon atom. O₂ and CO₂ are nonpolar molecules because they contain only nonpolar bonds, and CCl₄ is also nonpolar because the polar bonds (between carbon and chlorine atoms) cancel each other out due to the symmetrical tetrahedral arrangement of atoms around the central carbon atom.
