This question already has an answer here:
Consider the following compound:
The name engraved below it is what ACD ChemSketch generated for me. However, my book mentions that "3-chlorotoluene" is the iupac name for this compound.
This is another compound:
My book mentions "2,4,6-trichlorotoluene" is the IUPAC name, while the above is the name generated by ChemSketch.
Now, I am confused as to which name to agree with.
Which name is correct?
Which IUPAC rule says that toluene (and other related siblings like phenol) should be/should not be a part of the IUPAC name?
NOTE: I know that even common names can be considered as PINs, but in my post I am dealing with systematic IUPAC name only.
