The bond energy for a CH bond is about 413 kJ/mol in CH4 but 380 kJ/mol in CHBr3. Although these values are relatively close in magnitude, they are different. Explain why they are different. Does the fact that the bond energy is lower in CHBr3 make any sense? Why?

1 Chemistry Notes- Week 4 Quantum Theory 1. Atoms and photons at the microscopic level do not measure equally to the microscopic level 2. The laws for macroscopic are not applicable to the microscopic level 3. All energy is transferred through the measure of waves (E = h x v) 4. E = h x v means energy is calculated by multiplying Planks Constant (6.63 x 10^-34 J x s) by the frequency The Schrodinger Equation 1. Erwin Schrodinger realized the wave and particle characteristics were different in electrons 2. Particle behavior is determined by mass (m) while wave behavior is determined by the wave function (Ψ) in the equation H (m
