An organic compound (C 8 H 10 O 2 ) rotates plane-polarized light. It produces pink color with neutral FeCl 3 solution. What is the total number of all the possible isomers for this compound?
Text Solution
Verified by Experts6
(6) (Considering that all isomers satisfy the given conditions)
Since given compound produces pink colour with neutral FeCl 3 .
So, it must have at least one -OH group attached to benzene ring.
Also, given compound is optically active, it means it should have a chiral centre, which is only possible whenithas-CH(OH)CH 3
So, based on the above observations, compound (C 8 H 10 O 2 ) is expected to possess the following isomeric structures.

So, total isomeric structures = 6
