among these, which are acceptable IUPAC names,
2. The attempt at a solution
1)First option seems correct but is chlorine a higher priority group than methyl?? or does chlorine get a lower number due to alphabetical order?
2)toluene is accepted by IUPAC so correct
3)I see no reason as to why this should be incorrect
4)if methyl has higher priority then correct, if there is no such priority and alphabetical arrangement is followed in this case then incorrect- besides doesn't the name chlorobenzene imply chlorine is at position 1?
I'd be very grateful for some insight
