Hint: The chirality center or chiral center is a tetrahedral atom with hybridization which is usually a carbon atom. The carbon atom is attached to four different atoms or groups.
Complete step by step answer:The chiral centers are the tetrahedral atoms that are attached with four different atoms or substituent. Each chiral center in a molecule will be either R or S configuration as they are optically active. The optically active compounds are those which can rotate the plane polarized light either in clockwise or anticlockwise. R configuration means rotation towards clockwise and S configuration means rotation towards counterclockwise or anticlockwise.
The most common chiral atom is carbon as it is tetravalent in nature it can form four bonds and can attach four different atoms. It is hybridized. The other atoms which are chiral in nature are quaternary nitrogen, tertiary nitrogen.
The chiral molecule contains one carbon atom attached to four non-identical atoms or groups. The carbon is considered as the chiral center. The chiral center is also known as stereogenic center. The chiral compounds are non-symmetric in nature thus they are non-superimposable mirror images.
Example of a chiral compound is shown below.
Here the carbon atom is attached to chlorine, fluorine, bromine and hydrogen. The carbon is the chiral center and the compound is the chiral compound.
Note:
Meso compounds are exceptions as they contain multiple chiral centres but are achiral in nature. The compound containing double bonds cannot have chiral centers as four double bonds cannot be bonded to one carbon atom.
