Given that the average bond energies for C- H and C- Br bonds are 413 and 276 kJ/mol, respectively, the heat of atomization of bromoform (CHBr₃) is _ kJ/mol. A) 1241 B) 1378 C) - 689 D) 689 E) - 1378

Question

Quizplus · Accepted Answer

The heat of atomization is the energy required to break all the bonds in a molecule to form individual atoms. Bromoform (CHBr3) has one C-H bond and three C-Br bonds. The total energy required is (1 * 413) + (3 * 276) = 413 + 828 = 1241 kJ/mol.
