Helium Polarity Helium Polarity Helium (CAS 7440-59-7) is an element, so molecular polarity does not apply. He is symmetric, so its bond dipoles cancel and μ = 0 D exactly Covers geometry, comparison data, QC strategy and B2B sourcing notes for industrial buyers.
Thionyl tetrafluoride Polarity Thionyl tetrafluoride Polarity Thionyl tetrafluoride (CAS 13709-54-1) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA 1.34 (Crippen calculated, RDKit).
Formate ion Polarity Formate ion Polarity Formate ion (CAS 71-47-6) 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 sourcing.
Acetonitrile Polarity Acetonitrile Polarity Acetonitrile (CAS 75-05-8) is polar. C2H3N has a literature gas-phase dipole of about 3.92 D, which follows from its linear carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.53 (Crippen calculated, RDKit).
Calcium chloride Polarity Calcium chloride Polarity Calcium chloride (CAS 10043-52-4) 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.
Propene Polarity Propene Polarity Propene (CAS 115-07-1) is polar. C3H6 has a calculated dipole of about 0.39 D, which follows from its trigonal planar carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA 1.19 (Crippen calculated, RDKit).
Tetrachloroethylene Polarity Tetrachloroethylene Polarity Tetrachloroethylene (CAS 127-18-4) is nonpolar. C2Cl4 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00373 (gas estimate). Covers geometry, comparison data, QC strategy and.
Boron tribromide Polarity Boron tribromide Polarity Boron tribromide (CAS 10294-33-4) is nonpolar. BBr3 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00531 (gas estimate). Covers geometry, comparison data, QC strategy and.
Arsenic pentafluoride Polarity Arsenic pentafluoride Polarity Arsenic pentafluoride (CAS 7784-36-3) is nonpolar. AsF5 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.22516 (gas estimate).
Argon Polarity Argon Polarity Argon (CAS 7440-37-1) is an element, so molecular polarity does not apply. Ar is symmetric, so its bond dipoles cancel and μ = 0 D exactly Covers geometry, comparison data, QC strategy and B2B sourcing notes for industrial buyers.
