Question 12 0.67 / 2 pts Why is 1,2-dimethoxyethane used as solvent in the Diels-Alder reaction? (Check all that apply) It has a higher boiling point than diethyl ether. It is a nonpolar solvent. It is more polar and dissolves the anthranilic acid better. It is completely miscible with water It causes the product to preciptate during the reaction.
Incorrect Question 6 0/2 pts What is the main reason that absolute ethanol is used in the synthesis of TPCP? Absolute ethanol does not contain water. The reactants dissolve better in absolute ethanol. Absolute ethanol is cheaper than 95% ethanol. The product is less soluble in absolute ethanol that in 95 % ethanol. Absolute ethanol has a higher boiling point that 95% ethanol. Incorrect Question 7 0/2 pts Why is tetraphenylcyclopentadienone dark purple? It displays an absorbance at 330 nm. It displays an emission at 500 nm. It displays an absorbance at 500 nm. It displays an absorbance at 400 nm. It displays an emission at 400 nm.
