Among the molecules listed, NO (nitric oxide) is polar. This is due to the difference in electronegativity between nitrogen and oxygen, which creates a dipole moment. In contrast, BCl3 (boron trichloride) is nonpolar because of its symmetrical trigonal planar shape, while N2 and O2 are diatomic molecules consisting of identical atoms, making them nonpolar as well.
