[quote=@Caits] Thank you. And then there's the love triangle with the hydrogen twins and oxygen. And then carbon and hydrogen quads. And carbon twins and the hydrogen triplets. Carbon, the hydrogen triplets and a halide. I could have fun with this. [@Leslie Hall] it's fine by me [/quote] I am always good for a laugh, either with me or at me. ;) Don't even mention the compicated acetate busness. Carbon sisters, hydrogen triplets, and the oxygen brothers... That is some epic stuff going on...
