Do eggs smell sulfur or does sulfur smell bad eggs?

No.

Bad eggs smell of hydrogen sulphide.

Sulfur being non-living is unable to smell. Depending on the embryo inside the egg it is possible it could detect the smell of sulfur.

That's a rather more subtle linguistic point than it looks.

 

perhaps I should have written

"Bad eggs smell of hydrogen sulphide."

The question is more depending on the point of view, do bad eggs smell sulfur, or does the sulfur as a gaz smell like bad eggs, because they are often associated one with each other, so wich is the basic smell that defines the other?

Eggs do not have to be 'bad' to have a sulfurous odor. The basic smell/odor is sulfurous, and eggs contain sulfur compounds and so eggs may have a smell/odor of sulfur.

 

Where Does the Sulfur Hide in those Eggs? @ OChef

...Once again Ochef must step in to set the record straight. The USDA does not reference the sulfur content of foods because it is itself a component of several amino acids and vitamins, which the USDA does quantify. At least two of those amino acids methionine and cystine are present in both the yolk and white of the egg, so sulfur is also present in both parts. ...

You need to sort out the grammar here

There's a difference between "do bad eggs smell sulfur" which is nonsense- sulphur doesn't have a nose- and "do bad eggs smell of sulfur".

 

Also since sulphur is a non volatile solid, it doesn't smell.

But a lot of its compounds do.

I think it will help if I reworded the question and it is basically a chicken or egg (lol) question. Is the smell of hydrogen sulphide associated to the smell of bad eggs or the other way around?
