Calcium oxide Polarity Calcium oxide Polarity Calcium oxide (CAS 1305-78-8) 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).
n-Butane Polarity n-Butane Polarity n-Butane (CAS 106-97-8) is nonpolar. C4H10 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00252 (gas estimate). Covers geometry, comparison data, QC strategy and B2B.
Beryllium Polarity Beryllium Polarity Beryllium (CAS 7440-41-7) is an element, so molecular polarity does not apply. Be is symmetric, so its bond dipoles cancel and μ = 0 D exactly Covers geometry, comparison data, QC strategy and B2B sourcing notes for industrial buyers.
Arsenic trifluoride Polarity Arsenic trifluoride Polarity Arsenic trifluoride (CAS 7784-35-2) 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).
Propyne (Methylacetylene) Polarity Propyne (Methylacetylene) Polarity Propyne (Methylacetylene) (CAS 74-99-7) is polar. C3H4 has a calculated dipole of about 0.63 D, which follows from its linear carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.64 (Crippen calculated, RDKit).
Silicon Polarity Silicon Polarity Silicon (CAS 7440-21-3) is an element, so molecular polarity does not apply. Si is symmetric, so its bond dipoles cancel and μ = 0 D exactly Covers geometry, comparison data, QC strategy and B2B sourcing notes for industrial buyers.
Selenium hexafluoride Polarity Selenium hexafluoride Polarity Selenium hexafluoride (CAS 7783-79-1) is nonpolar. SeF6 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant no value quoted. Covers geometry, comparison data, QC strategy and B2B.
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.
