Re: Hydrogen Sulphide doesn't stink
Off the top of my head I suspect you may be be slightly mis-remembering ... pure *methane* doesn't smell, but tends to contain contaminants that make it very smelly. (In the case of domestic gas, they actually add ethanethiol (ethyl mercaptan) or other sulfur compounds because non-smelly gas leaks are dangerous!) I think H2S does smell (but, when pure, not nearly as badly as people think - those are (similar) contaminants).
You are absolutely right about it being extremely toxic though.
