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 (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.

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 (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 (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 (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).
