| act_sci_001,act,science,physical_science,Alkanes are chemical compounds consisting of only carbon and hydrogen atoms. Two types of alkanes are n-alkanes (molecules in which the carbon atoms are bonded together to form a chain) and cycloalkanes (molecules in which the carbon atoms are bonded together to form a ring).
