Alright, let's write the condensed structural formulas for each of the given reactions step-by-step.
### a) Ethane to Ethene + Hydrogen
- Ethane is C2H6.
- Ethene is C2H4.
- Hydrogen is H2.
The reaction can be written as:
[tex]\[ \text{C}_2\text{H}_6 \rightarrow \text{C}_2\text{H}_4 + \text{H}_2 \][/tex]
### b) 4,4-Dimethylpent-2-yne + Hydrogen to Propene + 2-Methylpropane
- 4,4-Dimethylpent-2-yne is C7H10.
- Propene is C3H6.
- 2-Methylpropane is C4H10.
The reaction can be written as:
[tex]\[ \text{C}_7\text{H}_{10} + \text{H}_2 \rightarrow \text{C}_3\text{H}_6 + \text{C}_4\text{H}_{10} \][/tex]
### c) Methylbenzene + Oxygen to Carbon Dioxide + Water Vapour
- Methylbenzene (also known as toluene) is C7H8.
- Oxygen is O2.
- Carbon Dioxide is CO2.
- Water Vapour is H2O.
The balanced reaction can be written as:
[tex]\[ \text{C}_7\text{H}_8 + \frac{9}{2}\text{O}_2 \rightarrow 7\text{CO}_2 + 4\text{H}_2\text{O} \][/tex]
### d) Nonane to 1-Ethyl-3-Methylbenzene + Hydrogen
- Nonane is C9H20.
- 1-Ethyl-3-Methylbenzene is C9H12.
- Hydrogen is H2.
The reaction can be written as:
[tex]\[ \text{C}_9\text{H}_{20} \rightarrow \text{C}_9\text{H}_{12} + 4\text{H}_2 \][/tex]
So to summarize, the condensed structural formula equations for the given reactions are:
1. [tex]\( \text{C}_2\text{H}_6 \rightarrow \text{C}_2\text{H}_4 + \text{H}_2 \)[/tex]
2. [tex]\( \text{C}_7\text{H}_{10} + \text{H}_2 \rightarrow \text{C}_3\text{H}_6 + \text{C}_4\text{H}_{10} \)[/tex]
3. [tex]\( \text{C}_7\text{H}_8 + \frac{9}{2}\text{O}_2 \rightarrow 7\text{CO}_2 + 4\text{H}_2\text{O} \)[/tex]
4. [tex]\( \text{C}_9\text{H}_{20} \rightarrow \text{C}_9\text{H}_{12} + 4\text{H}_2 \)[/tex]
