Methylene (carbene) Polarity Methylene (carbene) Polarity Methylene (carbene) (CAS 2465-56-7) is nonpolar. CH2 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00066 (gas estimate). Covers geometry, comparison data, QC strategy and.
Calcium carbonate Polarity Calcium carbonate Polarity Calcium carbonate (CAS 471-34-1) 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.
1,2-Dichloroethane Polarity 1 2-Dichloroethane Polarity 1,2-Dichloroethane (CAS 107-06-2) is polar. C2H4Cl2 has a literature gas-phase dipole of about 1.40 D, which follows from its tetrahedral carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA 1.46 (Crippen calculated, RDKit).
Cyanogen bromide Polarity Cyanogen bromide Polarity Cyanogen bromide (CAS 506-68-3) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA 0.86 (Crippen calculated, RDKit). Covers geometry, comparison data, QC strategy and.
Bromine trichloride Polarity Bromine trichloride Polarity Bromine trichloride (CAS 12642-76-3) is polar. VSEPR gives 3 bonding domains and 2 lone pairs — asymmetric, so the dipoles do not cancel. Dipole moment non-zero; magnitude not calculated; dielectric constant no value quoted.
Bismuth triiodide Polarity Bismuth triiodide Polarity Bismuth triiodide (CAS 7787-64-6) 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).
Borohydride ion Polarity Borohydride ion Polarity Borohydride ion (CAS 16940-66-2) 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.
Boranide ion Polarity Boranide ion Polarity Boranide ion (CAS 25335-36-2) 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.
Hexafluoroarsenate(V) ion Polarity Hexafluoroarsenate(V) ion Polarity Hexafluoroarsenate(V) ion (CAS 17018-85-8) 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.
Arsenic hexafluoride Polarity Arsenic hexafluoride Polarity Arsenic hexafluoride (CAS 17435-33-5) is nonpolar. AsF6 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.
