WebA meso compound is a stereoisomer with two or more chiral centres but no optical activity due to an internal plane of symmetry. Mesomers are compounds with zero net rotation of plane polarised light. In other words, mesomers are organic molecules that have two chiral carbons that are identical, resulting in zero net rotation. WebBoth the left and right hand are chiral (ky-ral) and show chirality. Chiral is derived from the Greek word cheir, which means “hand”, and chirality means “handedness”.

WebChiral centers. An atom with four different groups bonded to it in such a way that it has a non-superimposable mirror image is called a chiral center. "The objects which are non-superimposable on their mirror image are said to be chiral and this property is known as chirality''. An example of chirality is a pair of hands. WebEnantiomers are pairs of stereoisomers that, in their three-dimensional projection, are related to one another as an object to its mirror image, and thus are not superimposable ().A typical example of familiar objects related in such a way are the right and left hand. Such nonsuperimposable objects are said to be chiral .The most common origin of chirality is …
