Definition of Levorotatory

A levorotatory compound is defined as an optically active chemical compound which can rotate the light which it is passed through it. This compound rotates the polarized light in a counter-clockwise direction. It is denoted by the symbols like / or -. This term is widely used in the fields of chemistry and physics. It is used in the determination of optical rotation of plane-polarized light.


The compounds which are levorotatory consist of chiral centres. If the chiral molecule is levorotatory (left-handed), then its enantiomer which is an exact mirror image will be dextrorotatory (right-handed), and vice versa. The extent of rotation of the polarized light depends on several factors like chiral centres, temperature, and wavelength of the light.
