HOT Topics

  • Phosphorus pentachloride Polarity
    Phosphorus pentachloride Polarity Phosphorus pentachloride Polarity Phosphorus pentachloride (CAS 10026-13-8) is nonpolar. PCl5 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00467 (gas estimate).
  • Nitrous oxide Polarity
    Nitrous oxide Polarity Nitrous oxide Polarity Nitrous oxide (CAS 10024-97-2) is polar. N2O has a literature gas-phase dipole of about 0.17 D, which follows from its linear nitrogen centre Snyder polarity index Not conventionally assigned; XlogP3-AA -0.16 (Crippen calculated, RDKit).
  • Hydrogen sulfide Polarity
    Hydrogen sulfide Polarity Hydrogen sulfide Polarity Hydrogen sulfide (CAS 7783-06-4) is polar. H2S has a literature gas-phase dipole of about 0.97 D, which follows from its bent sulfur centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.11 (Crippen calculated, RDKit).
  • Hydrogen peroxide Polarity
    Hydrogen peroxide Polarity Hydrogen peroxide Polarity Hydrogen peroxide (CAS 7722-84-1) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA 0.02 (Crippen calculated, RDKit). Covers geometry, comparison data, QC strategy and.
  • Formaldehyde Polarity
    Formaldehyde Polarity Formaldehyde Polarity Formaldehyde (CAS 50-00-0) is polar. CH2O has a calculated dipole of about 2.13 D, which follows from its trigonal planar carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA -0.18 (Crippen calculated, RDKit).
  • Acetylene Polarity
    Acetylene Polarity Acetylene Polarity Acetylene (CAS 74-86-2) is nonpolar. C2H2 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (literature gas-phase value; the dipoles cancel by symmetry); dielectric constant ≈1.00121 (gas estimate).
  • Xenon difluoride Polarity
    Xenon difluoride Polarity Xenon difluoride Polarity Xenon difluoride (CAS 13709-36-9) is nonpolar. XeF2 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.06650 (gas estimate). Covers geometry, comparison data, QC strategy and.
  • Phosphorus trichloride Polarity
    Phosphorus trichloride Polarity Phosphorus trichloride Polarity Phosphorus trichloride (CAS 7719-12-2) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA 2.93 (Crippen calculated, RDKit).
  • Oxygen difluoride Polarity
    Oxygen difluoride Polarity Oxygen difluoride Polarity Oxygen difluoride (CAS 7783-41-7) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA 0.77 (Crippen calculated, RDKit). Covers geometry, comparison data, QC strategy and.
  • Nitrite ion Polarity
    Nitrite ion Polarity Nitrite ion Polarity Nitrite ion (CAS 14797-65-0) 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.
