Interpretation:
Mechanism of compound are synthesized by the use of only provided carbon-containing compounds has to be given.
Concept introduction:
Required compounds are synthesized by the use of only provided carbon-containing compounds through a series of steps.
In first case, given alcohol is oxidized to a
In second case, given alcohol is oxidized to a ketone. A strong base is added to the ketone. Aldol condensation reaction takes place. Hydrazine in alcoholic potassium hydroxide is added in the aldol condensation product to remove the carbonyl group. The intermediate
In third case, ethanol is oxidized to acetaldehyde. Acetaldehyde undergoes aldol addition reaction in presence of a strong base. Aldol addition product is reduced to form a

Concept introduction:
Required compounds are synthesized by the use of only provided carbon-containing compounds through a series of steps.
In first case, given alcohol is oxidized to a ketone. A strong base is added to the ketone. Aldol condensation reaction takes place. The aldol product is reduced and the final compound is obtained.

Aldol condensation reaction takes place. Hydrazine in alcoholic potassium hydroxide is added in the aldol condensation product to remove the carbonyl group. The intermediate alkene is reduced to give the final compound.
In third case, ethanol is oxidized to acetaldehyde. Acetaldehyde undergoes aldol addition reaction in presence of a strong base. Aldol addition product is reduced to form a diol compound 1. Other alcohol is oxidized to an acetone and converted to diol compound 2. Compound 1 and 2 combine to form the final product and two molecules of water are reduced.

- The table includes macrostates characterized by 4 energy levels (&) that are equally spaced but with different degrees of occupation. a) Calculate the energy of all the macrostates (in joules). See if they all have the same energy and number of particles. b) Calculate the macrostate that is most likely to exist. For this macrostate, show that the population of the levels is consistent with the Boltzmann distribution. macrostate 1 macrostate 2 macrostate 3 ε/k (K) Populations Populations Populations 300 5 3 4 200 7 9 8 100 15 17 16 0 33 31 32 DATO: k = 1,38×10-23 J K-1arrow_forwardDon't used Ai solutionarrow_forwardIn an experiment, the viscosity of water was measured at different temperatures and the table was constructed from the data obtained. a) Calculate the activation energy of viscous flow (kJ/mol). b) Calculate the viscosity at 30°C.

The dominant macrostate or configuration of a system is the macrostate with the greatest weight W. Are both statements correct?arrow_forwardFor the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.arrow_forward
