Calculate the heat of atomization of furan in kJ/mol using the data provided. The heats of atomization for C, H, and O are 717, 218, and 249 kJ/mol, respectively, for each isolated atom.

A. 736 kJ/mol
B. 184 kJ/mol
C. 314 kJ/mol
D. 218 kJ/mol

Answer :

Final answer:

Using the provided heats of atomization for C (717 kJ/mol), H (218 kJ/mol), and O (249 kJ/mol), the calculated heat of atomization for furan (C4H4O) would be 3989 kJ/mol, which does not match any of the provided options, indicating possible errors in the data or options.

Explanation:

The student has asked to calculate the heat of atomization of furan using given heats of atomization for carbon (C), hydrogen (H), and oxygen (O). The heat of atomization is the energy required to break all bonds in a compound and separate its constituent atoms. To find the heat of atomization of furan, we first need to ascertain the molecular formula of furan, which is C4H4O. Next, using the provided data for the individual atoms:

Four carbon atoms: 4 × 717 kJ/mol = 2868 kJ/mol

Four hydrogen atoms: 4 × 218 kJ/mol = 872 kJ/mol

One oxygen atom: 1 × 249 kJ/mol = 249 kJ/mol

Adding these together, the total heat of atomization for furan is:

2868 kJ/mol + 872 kJ/mol + 249 kJ/mol = 3989 kJ/mol

However, none of the options given match the calculated number above. Thus, there seems to be a mistake either in the provided heats of atomization values or the options given for the answer. Due to this discrepancy, we cannot provide a confident answer to the student's question based on the provided data.
