Tin tetrachloride Polarity Tin tetrachloride Polarity Tin tetrachloride (CAS 7646-78-8) is nonpolar. SnCl4 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00364 (gas estimate). Covers geometry, comparison data, QC strategy and.
Silica gel Polarity Silica gel Polarity Silica gel (CAS 112926-00-8) is nonpolar. SiO2 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00135 (gas estimate). Covers geometry, comparison data, QC strategy and B2B.
Silicon carbide Polarity Silicon carbide Polarity Silicon carbide (CAS 409-21-2) 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).
Selenium oxychloride Polarity Selenium oxychloride Polarity Selenium oxychloride (CAS 7791-23-3) 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).
Scandium triiodide Polarity Scandium triiodide Polarity Scandium triiodide (CAS 13572-79-9) 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.
Dinitrogen dichloride Polarity Dinitrogen dichloride Polarity Dinitrogen dichloride (CAS 13444-72-9) is nonpolar. N2Cl2 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00203 (gas estimate).
Methyl cyanoacrylate Polarity Methyl cyanoacrylate Polarity Methyl cyanoacrylate (CAS 137-05-3) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA 0.24 (Crippen calculated, RDKit).
Malonic acid Polarity Malonic acid Polarity Malonic acid (CAS 141-82-2) is polar. C3H4O4 has a calculated dipole of about 2.58 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA -0.45 (Crippen calculated, RDKit).
Stearic acid Polarity Stearic acid Polarity Stearic acid (CAS 57-11-4) is polar. C18H36O2 has a calculated dipole of about 1.47 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 6.33 (Crippen calculated, RDKit).
Metasilicate ion Polarity Metasilicate ion Polarity Metasilicate ion (CAS 15593-54-1) 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.
