Remember guys, just about every compound known has some sort of "cousin".
Carbon dioxide is just one little ol' oxygen atom from carbon monoxide. Ethanol is a "cousin" of methanol.
And so on, and so forth...
Remember the Febreze urban legend that went around--Febreze killed cats and it contained an ingredient that was "one molecule away from antifreeze!!!" 😱
Just 'cause they "look" alike doesn't mean they act alike!
