Bromine trifluoride Polarity Bromine trifluoride Polarity Bromine trifluoride (CAS 7787-71-5) 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.
Sulfate ion Polarity Sulfate ion Polarity Sulfate ion (CAS 14808-79-8) 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. Covers geometry, comparison data, QC strategy and B2B.
Nitric oxide Polarity Nitric oxide Polarity Nitric oxide (CAS 10102-43-9) is polar. NO has a literature gas-phase dipole of about 0.16 D Snyder polarity index Not conventionally assigned; XlogP3-AA -0.45 (Crippen calculated, RDKit). Covers geometry, comparison data, QC strategy and B2B.
Boron trichloride Polarity Boron trichloride Polarity Boron trichloride (CAS 10294-34-5) is nonpolar. BCl3 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00312 (gas estimate). Covers geometry, comparison data, QC strategy and.
Carbonate ion Polarity Carbonate ion Polarity Carbonate ion (CAS 147-71-7) 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.
Dichloromethane Polarity Dichloromethane Polarity Dichloromethane (CAS 75-09-2) is polar. CH2Cl2 has a calculated dipole of about 1.53 D, which follows from its tetrahedral carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA 1.42 (Crippen calculated, RDKit).
Carbon tetrafluoride Polarity Carbon tetrafluoride Polarity Carbon tetrafluoride (CAS 75-73-0) is nonpolar. CF4 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00088 (gas estimate). Covers geometry, comparison data, QC strategy and.
Ethane Polarity Ethane Polarity Ethane (CAS 74-84-0) is nonpolar. C2H6 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00139 (gas estimate). Covers geometry, comparison data, QC strategy and B2B sourcing.
Borane Polarity Borane Polarity Borane (CAS 13283-31-3) is nonpolar. BH3 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00122 (gas estimate). Covers geometry, comparison data, QC strategy and B2B sourcing.
Phosphine Polarity Phosphine Polarity Phosphine (CAS 7803-51-2) is polar. PH3 has a literature gas-phase dipole of about 0.58 D, which follows from its trigonal pyramidal phosphorus centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.06 (Crippen calculated, RDKit).
