Question

78 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 triangle H degree = -2723.7 kJ. (a) Write a balanced equation for the combustion of 1 mol of C4H10O(l). (b) Write a balanced equation for the formation of C4H10O(l) from its elements. (c) By using the information in this problem and data in Table 5.3, calculate triangle H degree for diethyl ether.

Explanation / Answer

a) The combustion reaction is:

C4H10O + 6O2 --> 4CO2 + 5H2O

b) The formation reaction is:

8C + 10H2 + O2 --> 2C4H10O

c) I need the Table 5.3
