The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. Butenes are formed during the cracking (breaking down of large molecules) of petroleum to produce gasoline; they can also be prepared commercially by the catalytic dehydrogenation (elimination of hydrogen atoms from the molecule) of butanes. The formula is CH3CH2CH=CH2. ... and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure.
