An organic compound (C8H10O2) rotates plane-polarized light. It produces pink color with neutral FeCl3 solution. What is the total number of all the possible isomers for this compound?
DBE (Double bond equivalent) of C8H10O2 =Number of carbon atoms –Number of monovalent atoms)2+1=8–102+1=4
It gives pink colour with neutral FeCl3 solution. It means phenolic group should be present in the compound.
Note: C* represent chiral carbon. So it will have (d and l) optically active isomers.
Total optically active isomer = 6
