Benzyl mercaptan. Absolutely aweful. Doing a Parikh Doering oxidation on 1.4 kg material was interesting too. Close to 300g Me2S generated as
byproduct...

Of the chemicals I've used in my "lab," the best-smelling one is probably acetic acid (I just like the smell) and the worst is the odor produced when
you dump a mixture of acetic acid and sodium hypochlorite down the sink. I still haven't figured out what is being produced, exactly. When I write
the formula, hypochlorous acid seems logical, but I have read in many places that chlorine gas is produced. I guess that would account for the
burning feeling I get when breathing it.

Don't taste more than a little bit; it's poisonous.

Best: Acetone
Worst: Hydrogen Chloride (especially when dissolved with iron (II) or (III) chloride. Ammonia is also pretty bad.
Forgive my simple answers, I'm only a beginning chemist.

Don't taste the pure material; buy some wintergreen candies.

What in the unholy hell is the smell that comes off of sodium hydrosulfite in solution. It's abominable and more vile than hydrogen sulfide alone.

Sodium hydrosulfite? Do you mean sodium dithionite, Na2S2O4, or sodium bisulfite, NaHSO3? The latter only smells of SO2, which is pungent, but not
really bad. The former indeed has a very bad smell. In solution it decomposes and gives all kinds of sulphurous compounds, which are formed from a mix
of H2S and SO2 (polythionic acids, polysulfides), many of them are formed in your nose when SO2 and H2S dissolve at the same time and they are
perceived as having a truly foul smell.

Dithionite. I also hate SO2, but because it's choking and makes me sneeze uncontrollably when inhaled in any significant concentration.

Not the best or worst smelling, but I finished a synthesis of salicylamide and I've got to say... What a peculiar smell... Semi gross, semi
familiar...

I enjoy the smell of acetone and methanol, nice and sweet.
My worst would probably have to be NO2, that stuff just smells like you are about to die.
Ammonia can also be pretty bad, I cannot even discern a description for the smell of ammonia. It basically feels like being punched in the face with
odour.
Trichloroisocyanuric acid, TCCA, is one of the bad ones for me too; Really strong chlorine stench, even worse than actual chlorine.

I can personally attest that the analogous isopropyl compound has a nasty smell as well, at least at first. It diminishes with time.
The worst smell for me is carbonyl sulfide.

Hmm, I think this is because of impurities. I have some ACS grade potassium nitrate and it has no smell to me.

I have never found many compounds I enjoy because I find most smells overwhelming (the smell of apples and oranges make me want to vomit) but vanilin,
chloroform  (only a small whiff) and carbon dioxide smell absolutely wonderful.
I don't get why people say acetone smells so good, it makes me feel sick.

From the research I've done, it looks like you're inhaling carbon monoxide. I could be wrong though. Don't do this.

It has a faint smell. Open up a can of tonic water and smell. I think it might be the sensation more than the aroma though.

Try sticking your head in a chest of dry ice. I know the smell/sensation. Like accidentally getting coke (the beverage) up your nose...

To the above posts.
I wonder if impurity among nitrates is N2O since I also noticed the sweet smell of ammonium nitrate fertilizer.
Hypochlorite and acetic acid shouldn't be forming carbon monoxide if I remember correctly.
Inhaling something as cold as dry ice can't be healthy for the lungs either.

I didn't mean the dry ice itself, but the very rich CO2 atmosphere in the chest. Just be careful not to asphyxiate.

Is it just me or does Oxygen gas smell "fresh"? It's the only way I can describe it and I love it!

In my opinion the worst smelling compounds are triethyl amine , chloride and bromine just because of their strength but worst for smell of all the
halogens is F2 although ive only smelt it in small concentrations it really does have an unpleasant smell.

Call me weird but I love the smell of bromine.
I also like the smell of aluminum and copper sulfate.
