Question

would anyone be able to help me solve these questions? im unsure what its even asking

4When the starting material shown below is treated with a variety of bases in DMSO (solvent) at 50 C, the percentage of 1-butene formed among total butenes is found to be dependent on the choice of base, as seen in the chart below (J, Am. Chem. Soc. 1973, 95, 3405-3407). base +other products DMSO 2-jodobutane 1-butene 50°C Н,с Structure of Base FyC ethoxide 2,2,2-trifluoroethoxide Name of Base benzoate phenoxide % 1 - Butene (In Total Butenes) 17.1 14.3 11.4 7.2 Based on the observations recorded in the table: (a) Identify and discuss the trend observed by comparing the basicity of the bases, and then. describe the correlation between reactivity (base strength) and selectivity (specifically regioselectivity) in the total elimination products observed. Be sure to also include in your discussion the trends as they relate to the pKa's of the conjugate acid for each base examined.
