Concept explainers
Interpretation:
For the below compound the chirality centers has to be labeled and number of chiral centers should be determined.
Concept introduction:
Chirality center:
When a carbon atom is bonded to four different groups, then that carbon is named as chiral carbon and it is called as chirality center. Generally, the carbon atom contains tetrahedral valency, therefore it bonded to four atoms or molecules. The chiral center is bonded with four different elements or groups. If the single carbon atom is bonded to two or more identical group or atom, then it is also not considered as chiral carbon. In addition to this, if the carbon atom contains multiple bond then it does not able to bond with four different groups then it is not considered to be as a chirality center.
