I'm trying to figure out what the structure of this hydrocarbon is. I know it's an unsaturated hydrocarbon, but I'm having trouble giving it a name. I know it's double bonded. This is what it looks like, with the hydrogens satisfiying the rest of the carbons accordingly.
The name of that chemical is 1,3-butadiene. The full chemical formula is H2C=CH-CH=CH2. We can name it according to the IUPAC rules for naming organic compounds. It has a linear chain of four carbons so the name will be based on butane. There are no substituents off of this chain but there are two double bonds. So the name of the chemical will be based on butadiene We start numbering the carbons from one end to the other. Since the double bonds are on both ends, it does not matter which end you start counting from. So we number the carbons 1-4 from left to right. This puts the double bonds starting on carbons number 1 and 3. So the name of the chemical is 1,3-butadiene.
This 1.3-butadiene (butadiene). The first member of a homologous series of butadiene (conjugated diene hydrocarbons). Butadiene - a colorless gas with a characteristic odor, boiling point -4,5 ° C, the melting point of -108,9 ° C, the flash point of -40 ° C, the maximum permissible concentration in air (MPC) of 0.1 g / m ³, density 0.650 g / cm ³ at -6 ° C.
Slightly soluble in water, soluble in alcohol, kerosene and air in an amount 1,6-10,8%.
