(a)
Interpretation:
Synthesis of the given compound beginning with pentan-2-one is to be suggested.
Concept introduction:
The carbon–carbon bond-forming reaction results in heteroatoms having a specific relative positioning along the carbon backbone. If the heteroatoms in a target have 1, 2-, 1, 3-, 1, 4-, or 1, 5- relative positioning, and the synthesis calls for a carbon–carbon bond-forming reaction, then consider using a corresponding reaction from Table 19-1. In a retrosynthetic analysis, therefore, apply a transform that takes our target molecule back to reactants. Disconnect the appropriate C-C bond to take back to the reactants, and from retrosynthetic analysis, we can draw the synthesis of the target molecule.

- (9 Pts) In one of the two Rare Earth element rows of the periodic table, identify an exception tothe general ionization energy (IE) trend. For the two elements involved, answer the followingquestions. Be sure to cite sources for all physical data that you use.a. (2 pts) Identify the two elements and write their electronic configurations.b. (2 pts) Based on their configurations, propose a reason for the IE trend exception.c. (5 pts) Calculate effective nuclear charges for the last electron in each element and theAllred-Rochow electronegativity values for the two elements. Can any of these valuesexplain the IE trend exception?
