Ar=aromatic ring? (refers to aamc6 but is not question specific)

If the MCAT says Ar should I consider it to be an aromatic ring?

Question 140 on practice test 6 it refers to Ar3CX as an active halide, where Ar is apparently an abbreviation for aromatic ring. I've never seen this in my ochem classes or anywhere else.

It's an old test so maybe it's just an abbreviation that's not used anymore?

Yes.

ar3cx would be three phenyls attached to one carbon, which is also attached to a halide

The o-chem lab book I buy last year still use "Ar" when it imply aryl.

I guess I should have realized that anyways. Why would an Ochem question have argon in it. Dumb mistake.

My professors/lab TAs always used Ph so Ar is new to me. I'll have to remind myself of that on the test day.
