Correct statement(s) about dipole moment of R3NO and R3PO is/are : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

\mu1 > \mu2 due to higher difference in electronegativity of N and C than between P and C. \mu1' > \mu2' because 2p\pi - 3d\pi back bonding in the P—O bond decreases its dipole moment hence (R3NO)\mu > (R3PO)\mu. Hence, experimental dipole moment of R3PO < theoretical dipole moment of R3PO.
