What odor does hydrogen sulfide gas resemble?

Hydrogen sulfide gas is well-known for its distinctive odor, which is often described as resembling rotten eggs. This characteristic smell is particularly important for safety and detection because hydrogen sulfide is a highly toxic gas that can pose serious health risks even at low concentrations. Recognizing this odor helps individuals identify its presence and take appropriate precautions to avoid exposure.

The other choices represent different odors associated with various substances, but they do not accurately capture the specific smell of hydrogen sulfide. For example, burning rubber has a different and often acrid scent, sweet syrup tends to have a pleasant and sugary odor, and chemical solvents can have a wide range of smells that are not akin to rotten eggs. Thus, the unique association of hydrogen sulfide with the smell of rotten eggs is critical for awareness and safety in environments where this gas may be present.
