Explore the concepts of bond energy, wavelength calculation, DH determination, and hybrid bonding in organic molecules. Learn about the energetics behind chemical reactions and the significance of organic synthesis.
E N D
Consider just this part. How much E must be put in to make this occur? Br-Br bond energy is 193 kJ/mol.
What is the longest wavelength (in nm) of light that could make this reaction occur? Br-Br bond energy is 193 kJ/mol. h = 6.626 x 10-34 Js c = 3.00 x 108 m/s E= hc / l or l = hc/E • = hc/E = 6.626 x 10-34Js * 3.00 x 108 m/s * 1 x 109nm/m) 193000J/mol (1 mol/6.022 x1023 photons) l = 620. nm
What is the DH for this process? Is it energetically favorable? DH = Bonds broken – bonds made
Why Should We Care? Methyl t-butyl ether (MTBE) Organic synthesis allows us to make more complex molecules from relatively simple molecules. For example
Explicitly Draw the hybrid bonding of MTBE What are each of the bond angles? Draw the hybrid bonding for acetone.
