Web26 feb. 2024 · When two or more double bonds are present in a molecule, the fatty acid is said to be polyunsaturated. Generally, double bonds in mammalian polyunsaturated fatty acids (PUFAs) are separated by a methylene (−CH 2 −) group (“methylene-interrupted”). This structural property of PUFAs confers special chemical properties. WebBenzene is a planar molecule with six C―C bond distances of equal length. The observed bond distance (1.40 angstroms) is midway between the sp2 - sp2 single-bond distance (1.46 angstroms) and sp2 - sp2 double-bond distance (1.34 angstroms) seen in conjugated dienes and is consistent with the bond order of 1.5 predicted by resonance theory.
