Below are several constitutional isomers with the molecular formula C6H14. Which of these isomers will have the largest heat of combustion?

Transcript text: Below are several constitutional isomers with the molecular formula $\mathrm{C}_{6} \mathrm{H}_{14}$. Which of these isomers will have the largest heat of combustion?

Solution

Solution Steps

Step 1: Identify the Isomers

The given molecular formula is C8H18. The isomers shown are different structural arrangements of this formula.

Step 2: Understand Heat of Combustion

The heat of combustion is the energy released when a compound undergoes complete combustion with oxygen. For alkanes, the more branched the isomer, the lower the heat of combustion.

Step 3: Analyze the Structures
