Cyclotrisulfur Polarity Cyclotrisulfur Polarity Cyclotrisulfur (CAS 2045-71-4) is nonpolar. S3 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00246 (gas estimate). Covers geometry, comparison data, QC strategy and B2B.
Phosphorus pentabromide Polarity Phosphorus pentabromide Polarity Phosphorus pentabromide (CAS 7789-69-7) is nonpolar. PBr5 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00723 (gas estimate).
Sodium hydroxide Polarity Sodium hydroxide Polarity Sodium hydroxide (CAS 1310-73-2) is an ionic substance for which a molecular dipole moment is not defined. It is ionic: polarity shows up as charge separation and hydration, not as a molecular dipole.
Sulfur trifluoride anion Polarity Sulfur trifluoride anion Polarity Sulfur trifluoride anion (CAS 17176-89-7) is a molecular ion, for which "polar / nonpolar" is the wrong question. VSEPR gives 3 bonding domains and 2 lone pairs — asymmetric, so the dipoles do not cancel.
Phosphite ion Polarity Phosphite ion Polarity Phosphite ion (CAS 14901-63-4) is a molecular ion, for which "polar / nonpolar" is the wrong question. Its polarity follows from structure and symmetry rather than from a calculated dipole. Covers geometry, comparison data, QC strategy and B2B.
Difluoroiodate(I) ion Polarity Difluoroiodate(I) ion Polarity Difluoroiodate(I) ion (CAS 14696-81-2) is a molecular ion, for which "polar / nonpolar" is the wrong question. Its polarity follows from structure and symmetry rather than from a calculated dipole. Covers geometry, comparison data, QC strategy and.
Hydrogen selenide Polarity Hydrogen selenide Polarity Hydrogen selenide (CAS 7783-07-5) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA Not computed (Crippen parameters do not cover every element here).
Carbonyl fluoride Polarity Carbonyl fluoride Polarity Carbonyl fluoride (CAS 353-50-4) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA 1.05 (Crippen calculated, RDKit). Covers geometry, comparison data, QC strategy and.
Dimethyl ether Polarity Dimethyl ether Polarity Dimethyl ether (CAS 115-10-6) is polar. C2H6O has a calculated dipole of about 1.44 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.26 (Crippen calculated, RDKit).
Acetaldehyde Polarity Acetaldehyde Polarity Acetaldehyde (CAS 75-07-0) is polar. C2H4O has a calculated dipole of about 2.76 D, which follows from its trigonal planar carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.21 (Crippen calculated, RDKit).
