Answer:
ΔH°f(C₈H₁₈(g)) = -210.9 kJ/mol
Explanation:
Let's consider the combustion of C₈H₁₈.
C₈H₁₈(g) + 25/2 O₂(g) ⟶ 8 CO₂(g) + 9 H₂O(g) ΔH°rxn = − 5113.3 kJ
We can calculate the standard enthalpy of formation of C₈H₁₈(g) using the following expression.
ΔH°rxn = 8 mol × ΔH°f(CO₂(g)) + 9 mol × ΔH°f(H₂O(g)) - 1 mol × ΔH°f(C₈H₁₈(g)) - 25/2 mol × ΔH°f(O₂(g))
1 mol × ΔH°f(C₈H₁₈(g)) = 8 mol × ΔH°f(CO₂(g)) + 9 mol × ΔH°f(H₂O(g)) - 25/2 mol × ΔH°f(O₂(g)) - ΔH°rxn
1 mol × ΔH°f(C₈H₁₈(g)) = 8 mol × (-393.5 kJ/mol) + 9 mol × (-241.8 kJ/mol) - 25/2 mol × 0 kJ/mol - (− 5113.3 kJ)
ΔH°f(C₈H₁₈(g)) = -210.9 kJ/mol
The correct option is (d) Nonane.
Nonane parent chain of the following compound.
<h3>What are hydrocarbons?</h3>
Hydrocarbons are any of a group of organic compounds that exclusively contain the elements carbon (C) and hydrogen (H) (H). The structural framework of the molecule is formed by a number of interactions between the hydrogen and carbon atoms.
<h3>What is hydrocarbon made of?</h3>
Hydrocarbons, which are only composed of carbon and hydrogen, make up the majority of crude oil, refined petroleum hydrocarbons (including gasoline, diesel, kerosene, fuel oil, and lubricating oil), coal tar, creosote, dyestuff, and pyrolysis waste products.

You should avoid it because there are hazards to consider when you are doing a laboratory experiment. For example the sleeves might catch in fire , you spilled a corrosive solution in yourself.
