So, overall, you get SO2 … Formal charge calculation can be done using:- Now let’s see the lewis structure of SO2. The toxicity of H2S is largely dependent on its ability to shut down the nervous system. Perhaps the shortest and easiest explanations given these differences is that at lower levels sulfur dioxide can be described as a more corrosive irritant—especially when the lungs are concerned—and at moderately higher levels hydrogen sulfide can be described as an effective neurotoxin. Hydrogen sulfide is the chemical compound with the formula H 2 S.It is a colorless chalcogen hydride gas with the characteristic foul odor of rotten eggs.
