Give the general formula of the alkenes.
Name the alkene shown.
Explain how this structure demonstrates that alkenes are: unsaturated hydrocarbons
Alkenes are made when some fractions from the fractional distillation of petroleum (crude oil) are cracked. State the meaning of the term cracking.
Carbon monoxide is produced when alkenes undergo incomplete combustion. State one effect of carbon monoxide on health.
A compound is made up of 22.2% carbon, 3.70% hydrogen and 74.1% bromine by mass. Calculate the empirical formula of this compound.
A separate compound containing carbon, hydrogen and bromine has empirical formula $\text{C}_3\text{H}_2\text{Br}$. The relative molecular mass of this compound is 236. Deduce the molecular formula of this compound.
