Sulfuric acid Polarity
Sulfuric acid
Polarity
Sulfuric acid (CAS 7664-93-9) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA -0.65 (Crippen calculated, RDKit). Covers geometry, comparison data, QC strategy and B2B.
-
Perchlorate ion Polarity
Perchlorate ion
Polarity
Perchlorate ion (CAS 14797-73-0) 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.
-
Acetic acid Polarity
Acetic acid
Polarity
Acetic acid (CAS 64-19-7) is polar. C2H4O2 has a calculated dipole of about 1.66 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.09 (Crippen calculated, RDKit).
-
Chloromethane Polarity
Chloromethane
Polarity
Chloromethane (CAS 74-87-3) is polar. CH3Cl has a calculated dipole of about 1.76 D, which follows from its tetrahedral carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.85 (Crippen calculated, RDKit).
-
Bromine Polarity
Bromine
Polarity
Bromine (CAS 7726-95-6) is nonpolar. Br2 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 ≈1.00219 (gas estimate).

Acetone Polarity
Acetone
Polarity
Acetone (CAS 67-64-1) is polar. C3H6O has a calculated dipole of about 3.04 D, which follows from its trigonal planar carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.60 (Crippen calculated, RDKit).

Sulfite ion Polarity
Sulfite ion
Polarity
Sulfite ion (CAS 14265-45-3) 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.

Hydroxide ion Polarity
Hydroxide ion
Polarity
Hydroxide ion (CAS 14280-30-9) 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.
