Isomers are molecules that have the same chemical formula but different arrangements of atoms, as shown here for two isomers of pentane, C₅H₁₂.

(a) Do you expect a significant difference in the enthalpy of combustion of the two isomers? Explain.

Hello everyone today. We have the following problem. Consider the to its members of C6 H 14 below. Will there be a significant difference in the entropy of combustion? Of these two ice hammers? So first we have to see what their chemical formulas are. So the one on the left has six carbons and 14 hydrogen. The one on the right also has six carbons, and it also has 14 hydrogen. So they have the same chemical formula. So same formula is going to indicate that the equation for the combustion reaction to the equation for the combustion reaction will be the same. The only difference is going to be the calculation for the entropy of the combustion. The values are gonna be very similar. So no, there will be no significant difference, no significant difference. And with that we have our final answer. I hope this helped. And until next time.
