Optical activity class 12 chemistry

Optical activity is measured by a polarimeter and depends on several factors, 1. concentration of the sample 2. temperature 3. length of the sample tube or cell and 4. the wavelength of the light passing through the sample. Rotation is given in + /- degrees, based on whether the sample contains d-(positive) or l … See more In this process, a carbocation, which is stabilized by resonance, is formed by the elimination of an electron withdrawing group. The carbocation has a planar structure which … See more Racemisation is defined as “a process by which an optically active substance either dextro or levorotatory, is directly converted into a racemate”. Resolution is the method when a racemic modification is divided into its constituent … See more Chirality is defined as “an object which is asymmetric and cannot be superimposed over its mirror image is known as chiral or stereocenter”. This property is known as chirality. For example-our hands, legs etc. The object which is … See more WebOptical activity is a macroscopic property of a collection of these molecules that arises from the way they interact with light. Compounds, such as CHFClBr, that contain a single stereocenter are the simplest to understand. One enantiomer of these chiral compounds is dextrorotatory; the other is levorotatory.
