The synthesis of 6–methyl–5–hepten–2–one from methyl– 4–oxo pentanoate is to be given. Concept introduction: The synthesize required can be carried out by the following steps. i) Protecting the keto group in the ketoester by treating with a diol ii) reduction of the ester to a primary alcohol iii) oxidation of the primary alcohol to aldehyde iv) Wittig reaction of the aldehyde with a phosphorus ylide. v) removal of the acetol linkage by hydrolysis. To give: The synthesis of 6–methyl–5–hepten–2–one from methyl– 4–oxo pentanoate.

Question

Laser. Indicate the relationship between metastable state and stimulated emission.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Laser. Indicate the relationship between metastable state and stimulated emission.

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-1
