Arsenide ion Polarity
Arsenide ion
Polarity
Arsenide ion (CAS 22541-49-9) is a monatomic ion, for which a dipole moment is not defined. Its polarity follows from structure and symmetry rather than from a calculated dipole. Covers geometry, comparison data, QC strategy and B2B sourcing notes.

Allyl cation Polarity
Allyl cation
Polarity
Allyl cation (CAS 1724-80-1) 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.

Adenine Polarity
Adenine
Polarity
Adenine (CAS 73-24-5) is polar. C5H5N5 has a calculated dipole of about 6.18 D, which follows from its bent nitrogen centre Snyder polarity index Not conventionally assigned; XlogP3-AA -0.06 (Crippen calculated, RDKit).
-
Acetic anhydride Polarity
Acetic anhydride
Polarity
Acetic anhydride (CAS 108-24-7) is polar. C4H6O3 has a calculated dipole of about 4.69 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.10 (Crippen calculated, RDKit).

Acetanilide Polarity
Acetanilide
Polarity
Acetanilide (CAS 103-84-4) is polar. C8H9NO has a calculated dipole of about 3.46 D, which follows from its trigonal planar carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA 1.64 (Crippen calculated, RDKit).
-
2-Pentene Polarity
2-Pentene
Polarity
2-Pentene (CAS 109-68-2) is nonpolar. It is nonpolar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA 1.97 (Crippen calculated, RDKit). Covers geometry, comparison data, QC strategy and B2B.
-
Tetrahydrofuran Polarity
Tetrahydrofuran
Polarity
Tetrahydrofuran (CAS 109-99-9) is polar. C4H8O has a calculated dipole of about 1.80 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 0.80 (Crippen calculated, RDKit).
