WebA compound is considered to be optically active if linearly polarized light is rotated when passing through it. The amount of optical rotation is determined by the molecular structure and concentration of chiral molecules in the substance. Each optically active substance has its own specific rotation as defined in Biots law: Biots Law WebMar 8, 2016 · The compound has two chiral carbons, so it will be optically active. 1,2-Dichloro-2-methylpentane. The structure of 1,2-dichloro-2-methylpentane is. Here, #"C2"# is a chiral carbon. The 4 groups attached to #"C2"# are #"CH"_3", Cl, CH"_2"Cl"#, and #"CH"_2"CH"_2"CH"_3#. The compound has a chiral carbon, so it will be optically active.

A sample containing 1.00 g/mL of the compound in a 1 dm tube exhibits an optical rotation of 3.5 o in clockwise direction. Note that the instrument used in Chem 30BL and Chem 30CL can provide the specific optical rotation, which already …
WebA different arrangement of a phenyl group and two bicyclic optically active fragments has been prepared from hydroxyethylglycine ligands and 1,4-phenylenediboronic acid [14] (Fig. 32). WebPure enantiomers also exhibit the phenomenon of optical activity and can be separated only with the use of a chiral agent. In nature, only one enantiomer of most chiral biological compounds, such as amino acids (except glycine, which is achiral), is present. An optically active compound shows two forms: D-(+) form and L-(−) form. Diastereomers
