When one molecule of pentane (C5H12\text{C}_5\text{H}_{12}C5H12) is cracked, three of the possible reactions are:
Reaction 1: C5H12→C3H6+C2H6 \text{Reaction 1: } \text{C}_5\text{H}_{12} \rightarrow \text{C}_3\text{H}_6 + \text{C}_2\text{H}_6 Reaction 1: C5H12→C3H6+C2H6 Reaction 2: C5H12→C4H8+CH4 \text{Reaction 2: } \text{C}_5\text{H}_{12} \rightarrow \text{C}_4\text{H}_8 + \text{CH}_4 Reaction 2: C5H12→C4H8+CH4 Reaction 3: C5H12→C5H10+H2 \text{Reaction 3: } \text{C}_5\text{H}_{12} \rightarrow \text{C}_5\text{H}_{10} + \text{H}_2 Reaction 3: C5H12→C5H10+H2One product in each of these reactions is an alkene. What is the general formula for the homologous series of alkenes?
What are the IUPAC names of the two products of Reaction 1?
Identify the saturated product of Reaction 2 and write its molecular formula.
The alkene product of Reaction 2, C4H8\text{C}_4\text{H}_8C4H8, has three main acyclic structural isomers that are alkenes. State the IUPAC names of these three isomers.
