Options
- ABenzene-1,2,3-triol
- BBenzene-1,5,6-triol
- CBenzene-1,3,5-triol
- DBenzene-2,3,4-triol
Correct answer
A. Benzene-1,2,3-triol
Step-by-step solution
The given organic compound consists of a benzene ring with three hydroxyl ( -OH ) groups attached to it. According to IUPAC nomenclature rules, the numbering of the carbon atoms in the benzene ring should be done in such a way that the substituents get the lowest possible locants. Starting the numbering from one of the terminal -OH bearing carbon atoms and moving towards the others gives the locants 1, 2, and 3 . Any other numbering scheme would result in higher locants (e.g., 1, 5, 6 or 2, 3, 4 ), which violates t
