Hydrogen Cyanide Polarity Hydrogen Cyanide Polarity Hydrogen Cyanide (CAS 74-90-8) is strongly polar. Linear H-C=N with distinct ends leaves the large C=N dipole uncancelled. Dipole moment ~ 2.99 D; dielectric constant ≈114.9 (liquid, 20 °C). Covers geometry, comparison data, QC strategy and B2B.
Carbon Monoxide Polarity Carbon Monoxide Polarity Carbon Monoxide (CAS 630-08-0) is formally polar but effectively nonpolar. Heteronuclear diatomic with a 0.110 D dipole whose negative end lies on carbon. Dipole moment 0.110 D; dielectric constant ≈1.00065 (gas).
Methane Polarity Methane Polarity Methane (CAS 74-82-8) is nonpolar. Four identical C-H bonds cancel by Td tetrahedral symmetry. Dipole moment 0 D; dielectric constant ≈1.0008 (gas). Snyder polarity index Not conventionally assigned; XlogP3-AA 0.6.
Water Polarity Water Polarity Water (CAS 7732-18-5) is strongly polar. Two lone pairs bend water to 104.5deg and each molecule donates and accepts two hydrogen bonds. Dipole moment 1.85 D; dielectric constant ≈80.1 (liquid, 20 °C).
Sulfur Dioxide Polarity Sulfur Dioxide Polarity Sulfur Dioxide (CAS 7446-09-5) is polar. One lone pair on sulfur bends the molecule to about 119deg, leaving the S=O dipoles uncancelled. Dipole moment 1.633 D; dielectric constant ≈1.008 (gas); ≈14.3 (liquid, 20 °C).
Carbon Dioxide Polarity Carbon Dioxide Polarity Carbon Dioxide (CAS 124-38-9) is nonpolar. Linear centrosymmetric O=C=O geometry cancels the two polar C=O bond dipoles. Dipole moment 0 D; dielectric constant ≈1.0009 (gas). Snyder polarity index Not conventionally assigned; XlogP3-AA 0.9.
