etyylieni
Etyylieni is a hypothetical organic compound with the chemical formula C2H4N2. It is a dinitrile, meaning it contains two nitrile functional groups (-C≡N). The name suggests a linear arrangement of two carbon atoms, with each carbon atom bonded to a nitrile group, and the remaining valencies satisfied by hydrogen atoms. However, the structure of etyylieni is not well-defined without further context. If the two carbon atoms are directly bonded, the formula would be NC-CN, which is known as cyanogen. If the carbon atoms are separated by other atoms, the structure would differ. For instance, if it were a derivative of ethane with nitrile groups, the formula might be interpreted as having two ethyl groups attached to nitrogen atoms, but this would not align with the C2H4N2 formula. The most straightforward interpretation of etyylieni as a dinitrile with two carbons points towards cyanogen (dicyanogen), a well-known and highly toxic gas. Cyanogen has a linear structure (N≡C-C≡N). Its properties are extensively documented. If etyylieni refers to a different isomer or a derivative not commonly known, further clarification of its structure would be necessary for a precise description.
