HOT Topics

  • Ethanimine / Acetonitrile Polarity
    Ethanimine / Acetonitrile Polarity Ethanimine / Acetonitrile Polarity Ethanimine / Acetonitrile (CAS 20729-41-3) is polar. C2H5N has a calculated dipole of about 1.89 D, which follows from its bent nitrogen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.66 (Crippen calculated, RDKit).
  • 1,2-Dibromoethene Polarity
    1,2-Dibromoethene Polarity 1 2-Dibromoethene Polarity 1,2-Dibromoethene (CAS 540-49-8) is nonpolar. C2H2Br2 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00331 (gas estimate). Covers geometry, comparison data, QC strategy and.
  • Perbromate ion Polarity
    Perbromate ion Polarity Perbromate ion Polarity Perbromate ion (CAS 16474-32-1) 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.
  • Bromine monofluoride Polarity
    Bromine monofluoride Polarity Bromine monofluoride Polarity Bromine monofluoride (CAS 13863-59-7) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA 1.27 (Crippen calculated, RDKit).
  • Benzoic acid Polarity
    Benzoic acid Polarity Benzoic acid Polarity Benzoic acid (CAS 65-85-0) is polar. C7H6O2 has a calculated dipole of about 1.94 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 1.38 (Crippen calculated, RDKit).
  • Beryllium bromide Polarity
    Beryllium bromide Polarity Beryllium bromide Polarity Beryllium bromide (CAS 7787-46-4) 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.
  • Arsenite ion Polarity
    Arsenite ion Polarity Arsenite ion Polarity Arsenite ion (CAS 15502-74-6) 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.
  • Urea Polarity
    Urea Polarity Urea Polarity Urea (CAS 57-13-6) is polar. CH4N2O has a calculated dipole of about 3.53 D, which follows from its trigonal planar carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA -0.98 (Crippen calculated, RDKit).
  • Selenium oxydifluoride Polarity
    Selenium oxydifluoride Polarity Selenium oxydifluoride Polarity Selenium oxydifluoride (CAS 14984-81-7) 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 tetrachloride Polarity
    Selenium tetrachloride Polarity Selenium tetrachloride Polarity Selenium tetrachloride (CAS 10026-03-6) 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).
