Solution: Diethyl ether, C4H10O (l), a flammable compound that has long been used as a surgical anesthetic, has the structure CH3 - CH2 - O - CH2 - CH3 The complete combustion of 1 mol of C4H10O (l) to CO2 (g) and H2O (l) yields Ho= -2723.7 kJ.By using the information in this problem and data in the following table, calculate HfHf for diethyl ether.

Problem

Diethyl ether, C4H10O (l), a flammable compound that has long been used as a surgical anesthetic, has the structure

CH3 - CH2 - O - CH2 - CH3

The complete combustion of 1 mol of C4H10O (l) to CO2 (g) and H2O (l) yields Ho= -2723.7 kJ.

By using the information in this problem and data in the following table, calculate HfHf for diethyl ether.
