The method for preparation of 1-penten-3-one from 3-pentanone is given. Concept introduction: When the α-Bromo ketones can be dehydrobrominated by base treatment to yield α,Î² unsaturated ketones. For example, 2-methyl cyclohexanone gives 2-bromo-2-methylcyclohexanone on halogenation and the α bromo ketone gives 2-methyl-2-cyclohexanone when heated in pyridine. To give: The preparation method of1-penten-3-one from 3-pentanone is given.

Question

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

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
