Trimethylamine Polarity
Trimethylamine
Polarity
Trimethylamine (CAS 75-50-3) is polar. C3H9N has a calculated dipole of about 0.90 D, which follows from its trigonal pyramidal nitrogen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.18 (Crippen calculated, RDKit).
-
Diiodomethane Polarity
Diiodomethane
Polarity
Diiodomethane (CAS 75-11-6) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA 1.81 (Crippen calculated, RDKit). Covers geometry, comparison data, QC strategy and B2B.

Calcium iodide Polarity
Calcium iodide
Polarity
Calcium iodide (CAS 10102-68-8) 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. Covers geometry, comparison data, QC strategy and.
-
Cyclobutadiene Polarity
Cyclobutadiene
Polarity
Cyclobutadiene (CAS 1120-53-2) is nonpolar. C4H4 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00224 (gas estimate). Covers geometry, comparison data, QC strategy and B2B.
-
Ethynyl radical Polarity
Ethynyl radical
Polarity
Ethynyl radical (CAS 2122-48-7) is polar. C2H has a calculated dipole of about 2.33 D, which follows from its linear carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.21 (Crippen calculated, RDKit).
-
Borate ion Polarity
Borate ion
Polarity
Borate ion (CAS 15537-73-2) 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 B2B sourcing.
-
Boron nitride Polarity
Boron nitride
Polarity
Boron nitride (CAS 10043-11-5) 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).
-
Acrylonitrile Polarity
Acrylonitrile
Polarity
Acrylonitrile (CAS 107-13-1) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA 0.70 (Crippen calculated, RDKit). Covers geometry, comparison data, QC strategy and B2B.

4-Aminophenol Polarity
4-Aminophenol
Polarity
4-Aminophenol (CAS 123-30-8) is polar. C6H7NO has a calculated dipole of about 2.05 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.97 (Crippen calculated, RDKit).
