4. Propose a Synthesis for the molecule below. You may use any starting materials containing 6
carbons or less (reagents that aren't incorporated into the final molecule such as PhзP do not
count towards this total, and the starting material can have whatever non-carbon functional
groups you want), and any of the reactions you have learned so far in organic chemistry I, II, and

Assume that the energy required to break a hydrogen bond is approximately 8 kJ/mol. Consider a simplified two-state model where a "formed" hydrogen bond is in the ground state and a "broken" bond is in the excited state. Using this model: • Calculate the fraction of broken hydrogen bonds at T = 300 K, and also at T = 273 K and T = 373 K. • At what temperature would approximately 50% of the hydrogen bonds be broken? • What does your result imply about the accuracy or limitations of the two-state model in describing hydrogen bonding in water? Finally, applying your understanding: • Would you expect it to be easier or harder to vaporize water at higher temperatures? Why?
