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.
(b) Which isomer do you expect to have the higher standard molar entropy? Explain.
Sketch the line-bond structure for each molecule or polyatomic ion of the following. Designate the formal charges where applicable.
