(a)

Interpretation Introduction

Interpretation:

A major product in the given reaction should be found.

Concept Introduction:

The resonance gives for α,β- unsaturated carbonyl compound which shoes that the compound has two electrophilic positions are β- carbon and carbonyl carbon.  That is a nucleophile can be add either to β- carbon or carbonyl carbon.  Conjugate addition and direct addition are depending upon the nature of the nucleophile.

Nucleophilic addition to the β- carbon (conjugate addition) is irreversible.

Nucleophilic addition to the carbonyl carbon (direct addition) is irreversible or reversible.  When nucleophile is weak base such as alcohol, an amine or thiol, then direct addition is reversible, because of weak base is worthy leaving group.

For a certain gas-phase reaction at constant pressure, the equilibrium constant Kp is observed to double when the temperature increases from 300 K to 400 K. Calculate the enthalpy change of the reaction, Ah, using this information.
Hydrogen bonding in water plays a key role in its physical properties. 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? If you were to hang wet laundry outside, would it dry more quickly on a warm summer day or on a cold winter day, assuming humidity is constant?
