Electron withdrawing groups (NO2, carbonyls, etc.) are mostly meta-directing and ring deactivating.

Electron donating groups (CH3, OH, etc.) are mostly ortho,para-directing and ring activating.

An exception are the halides (Cl, Br, etc.) which are ortho,para-directing yet ring deactivating.

I could however be 100%, completely wrong.

If the ketone is 1 carbon away (ex: benzaldehyde) then it will be meta directing. If the ketone is directly attatched (ex: benzanone) then it can donate into the resonance system and will be ortho/para. I may be wrong but that's how I understood it.

you need to realize what you saying, a ketone can NEVER be attached to the benzene ring directly.

also, anything with a carbonyl gp is a meta director and ring diactivator.

if you have the destroyer, read it it makes it very clear and list all the o, p, and m director

I think he's referring to "ketone" as any carbonyl group attatched to the ring. I figured that this is what he was talking about but did not make mention of it.

but if you just think, the directors are only applied to BENZENE rings !!!

anyway, i hope u will not do this mistake in the exam, do ypur mistakes now and not on the exam, this is the best tip i can give to you and everybody else.
