Broadly speaking there are four types of stereisomers namely conformational isomers geometrical isomers, enantiomers and diastereomers.Although conformational isomers , have same configuration geometrical isomers have different atoms attached to each of the doubly bonded carbon atom, and enantiomers are due to chirality in the molecule Enantiomers are also known as optical isomers and diastereomers are those stereoisomers which are not enantiomers.In simple compound, number of stereoisomers.In chiral molecule is given by the reaction 2^n, where n is the number of dissimilar chiral carbon. Observe the following structures and answer the questions given below : The correct names for the above structure is :

Answer»
