I hate:
Cl2
Br2
H2S
ethylamine,diethylamine, triethylamine and other amines
chloropirin (I just hate that chemical smell)
NO2
HN3
Phenol
methyl ethyl ketone
PH3
acetone peroxide smel is somewhere in the middle of the list. I can't decide if I like it or not. It smells so interestingly-confusing 
It is associated with the smell of danger, the smell I don't want to be around, but it smells quite pleasant and fresh :S
I love:
the smell of burning gunpowder
burning black powder(that SO2 smell brings back some nice memories from my childhood)
burning matches(same as gunpowder)
benzaldehyde (in low concentrations)
propiophenone (in low concentrations)
ether
ammonia smells nice in low concentrations
nitric acid
methyl and ethyl iodide
ethyl acetate
dichloromethane
isopropyl nitrate
dinitrotoluene (so sweet....)

Biodiesel, alkyl amides, and dilute methyl esters are my tops for smell...
As for worst, Id say P4S10 (evolves H2S and has its own distinct nasty smell), ethanethiol, strong ammonia, diphosphine, and diethyl ether (when the
vapour is very concentrated- and it often is for me, because I work at 9300ft, which is only 71.1kPa).

I'd have to say the smell i hate most is pyridine. Being in university labs at the undergraduate level, there's always someone doing organic synthesis
with pyridine every coupla weeks!
It's rather ironic in a way that pyridine gives instant and temporary infertility in men with just a sniff, and yet it smells quite alot like.....well
I'm sure i dont need to tell those of you that have experienced the smell...

That sounds like a bad rumor to me, I'd like to see a source.
Seems like that would have patents, etc on it if that were the case, and it would be easier to get! lol

Pyridine is a risk when you still want offspring, but it certainly is not the ideal method of sterilization of men. Just taking a whiff of a compound
and then being sterile for a certain period of time? No way

Isonitrile stench. Shrek Breath.
Regarding isonitriles - I had run across them some twenty years ago. Methyl isonitrile, used under a fume hood, still managed to sneak out a bit as
deposited on gloves/skin from volatilized CH3NC
It has a certain dental stink about it, a bad-breath character. Shrek breath.
The intensity, even from what devolatilized from a fume hood onto surfaces, was immense. If it were a fecal smell, I'd suggest that a full
porta-potty placed on a giant hot-plate and heated unto boiling - that degree of intensity.
I recall it was as equally toxic as cyanogen. Perhaps my recollection is wrong. Beware.

Had the great pleasure of working with hexamethyldisilathiane the past several months. It is exceedingly potent in its own right. Opening the bottle
to syringe out several microliters in the hood with the damper full open, and the sash down, I can still smell a distinct natural gas odour. My
Eppendorf and my gloves must stay in the hood for at least 2 days for the reek to be off of them. I imagine if I spilled a couple milliliters, the
neighbours downwind would probably think there was a natural gas leak.
Another stench I hate is morpholine. I also dislike butylamine and ethylenediamine. I also hate the smell of old DMF, and diisopropylcarbodiimide
(which many of you will argue that it is not something one should ever smell!).
Neither flask nor beaker.

Aniline - not a bad smell just an annoying one.
Anhydrous aluminium chloride - me thinks it doesn't emit
Cl2 it produces Cl.
The strangest odour - the better part of a lifetime ago...
I worked in the lab of a rendering plant... granted a
5-day old dead elephant doesn't smell like roses ...
the problem was the plant on the other side of the fence
that re-refined used car oil. Not a bad smell but it had
a curious effect — ever get pains in your stomach when
you were hungry? One whiff and you instantly got the same
felling.
For a God awful smell .... dead clams! Their odour will bring your breakfast up that fast.
Stumbled upon this a moment ago —
Angelic acid From the root of Anthemis nobilis by distillation.
Use: Flavoring extracts.
Wonder what it smells/tastes like.

Brings upon my mind this —
Suffocating Balls
"Are made in the same way as the smoke balls [dust of sea coal, pitch, fine
powder, nitre, and tallow]. The composition contains in addition, rasped horses'
and asses' hoofs, burnt in the hoof, assafatida [aka Devils dung], seraphine gum
&c."
No doubt -- these didn't smell like roses
SO: Manual of Military Pyrotechny for use of the Cadets
of the U.S. Military Academy, West Point. 1831
Several years back out of curiosity I bought 4-oz's
of asafoetida it has a funky smell.
http://en.wikipedia.org/wiki/Asafoetida
I am not planning on cooking with it. That said I do
like limburger cheese. Must have come from my
Prussian born grandfather. (186?)

You can never find a hippologist when you need one!
What prey-tell is — "burnt in the hoof"?

Uggg vanillin.... once so sweet.... getting to be so bitter.....
Not sure I will ever tire of benzaldahyde though since the smell is just heavenly.
Anyone else experiance a chemiphobe type reaction where after being around it to much it turns your stomach just thinking about it? Its really
becoming a problem considering I will almost throwup(have on one occassion) from looking at a vial of HgCl2. I now have to keep many reagents far out
of sight to avoid discomfort.

The WiZard is In: I would imagine burning hoofs smell like burning hair. I saw this on Dirty Jobs, thats how they install horse shoes!
SO2 isn't as bad as I thought it would be. Ammonia was pretty bad, smells like when you get a bloody nose. HCl is the worst of the three.
Iodine smells nice 
Oh yeah a relay exploded in my fridge and this horrible phenolic smell lingered for a few days.

The best would be:
Bromine-love it so much reminds me of summer, more so than chlorine which is kinda funny.
Ammonia- but I can only handle a little.
Acetic acid- Salt and vinegar anyone?
Benzaldehyde-very nice.
The worst would be:
SO2- I absolutely HATE this stuff the tinyest amounts make me cough and gag.
Formic acid: Hate it because it smells like SO2(anyone else notice that?) and because it gives terrible burns.
HNO3- I dont exactly "hate" this acid, but to me at least it kinda smells like BO which is why I dont really like it.
But In general I can tolerate the smells of almost any standard chemical, even some of the grosser ones.

Today I opened a new plastic bottle of potassium cyanate (KOCN). The smell was very.....hard to describe........special, fruity, sweet, interesting. I
just wanted to smell it a bit more, but judging by the chemical it might not be a god idea. It is probably some HCN.
One of my favorite smells so far.

Woah! be careful about sniffing the ethyl bromide, as I have a feeling you do not want that stuff hanging around your DNA! Also zajcek01 I do not
think you are going to have HCN evolving from any cyanate very easily, also for those who can smell it, HCN is described as having an almond odor not
really fruity.

Ohhh we made isoamyl acetate in high school. Maybe that's why I like chemistry so much.
The teacher brought in this old bottle that smelled like a dirty old man, then turned it into bananas.
We have this superglue at work that smells like candy. Well the activator does. Contains N,N-Dimethyltoluidine
