PLEASE ANSWER QUESTION IN 15 MINTUES NOT MORE PLEASE AND THANK YOU. If you do answer the question correctly and post it in the next 15 minutes, NO NEED TO SHOW THE WORK, I JUST WOULD LIKE THE CORRECT ANSWER AS SOON AS POSSIBLE. isnt the answer  e)none of theses since the correct : Structural Isomers   Optical isomers are the compounds which has the same number of atoms and bonds, but different type of spatial arrangement of bonds. The compounds as these isomers are non-superimposable mirror images of each other.    Structural isomers are the constitutional isomers in which two compounds has same molecular formula but different structures.      Stereoisomer are the compounds which have same number of atoms and bonds but differs by their spatial arrangement of atoms . Optical isomers are a type of stereo isomers.     Geometric isomers are the isomers which has same number of atoms and even same structural formula but these compounds differ in the arrangement of bonds. For example :…

Please see image for question. Please elaborate answer.

The second question was incorrect. "The IUPAC nomenclature of benzene compounds primarily will use benzene as the root name. However, common names for substituted benzene compounds exist that use the base names from its derived compounds. The principal functional group will serve as the common root name." Would you mind trying again please? Thank you

Please provide IUPAC names :)
