Identify the correct statements concerning dipole moment and molecular polarity. — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Statement C is incorrect; lone pair orbital dipoles heavily contribute to the net dipole moment (e.g., $NH_3$ vs $NF_3$). $CH_3Cl > CH_3F$ is a known exception due to bond length. $cis$ -isomers generally lack symmetry, adding dipoles, whereas $trans$ -isomers often cancel them out. Symmetrical molecules like $CCl_4$ have polar bonds but $\mu=0$.
