N02 iozo A) Why ethanol is NOT a suitable solvent for the preparation of a Grignard reagent with suitable explanation B) The benzoic acid could be extracted from the ether layer using sodium bicarbonate solution, write necessary equations showing this reaction. What practical reason makes this reaction less desirable than using sodium hydroxide during extraction? (4 points) Identify the strongest acid among the following and explain based on pKa values. Arrange them in increasing order of their pKa values (3 points) Acetic acid, Trichloroacetic acid, Trifluoroacetic acid, and Benzoic acid.
