Allene Polarity Allene Polarity Allene (CAS 463-49-0) is nonpolar. C3H4 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00181 (gas estimate). Covers geometry, comparison data, QC strategy and B2B sourcing.
Trifluoromethyl anion Polarity Trifluoromethyl anion Polarity Trifluoromethyl anion (CAS 34202-69-2) 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.
Dichlorocarbene Polarity Dichlorocarbene Polarity Dichlorocarbene (CAS 1605-72-7) is nonpolar. CCl2 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00183 (gas estimate). Covers geometry, comparison data, QC strategy and B2B.
Calcium fluoride Polarity Calcium fluoride Polarity Calcium fluoride (CAS 7789-75-5) 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.
Cyclohexane Polarity Cyclohexane Polarity Cyclohexane (CAS 110-82-7) is nonpolar. C6H12 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00340 (gas estimate). Covers geometry, comparison data, QC strategy and B2B.
1-Butyne / 1,3-Butadiene Polarity 1-Butyne 1,3-Butadiene Polarity 1-Butyne / 1,3-Butadiene (CAS 107-00-6 / 106-99-0) is polar. C4H6 has a calculated dipole of about 0.57 D, which follows from its tetrahedral carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA 1.03 (Crippen calculated, RDKit).
Ethylamine / Dimethylamine Polarity Ethylamine Dimethylamine Polarity Ethylamine / Dimethylamine (CAS 75-04-7 / 124-40-3) is polar. C2H7N has a calculated dipole of about 1.23 D, which follows from its trigonal pyramidal nitrogen centre Covers geometry, comparison data, QC strategy and B2B sourcing notes for.
Acetaldehyde / Ketene / Oxirene Polarity Acetaldehyde / Ketene / Oxirene Polarity Acetaldehyde / Ketene / Oxirene (CAS 463-51-4 / 157-18-6) is polar. C2H2O has a calculated dipole of about 1.81 D, which follows from its linear carbon centre Covers geometry, comparison data, QC strategy and B2B sourcing notes for industrial buyers.
Dibromoacetylene Polarity Dibromoacetylene Polarity Dibromoacetylene (CAS 4315-21-5) is nonpolar. C2Br2 is symmetric, so its bond dipoles cancel and μ = 0 D exactly Dipole moment 0 D (exact by symmetry); dielectric constant ≈1.00314 (gas estimate). Covers geometry, comparison data, QC strategy and.
Bromine pentachloride Polarity Bromine pentachloride Polarity Bromine pentachloride (CAS 21198-04-9) is polar. VSEPR gives 5 bonding domains and 1 lone pair — asymmetric, so the dipoles do not cancel. Dipole moment non-zero; magnitude not calculated; dielectric constant no value quoted.
