Answer 7) (e) All of the above
ANswer 8) True,log of partition coefficient used to generate polarity scale
Answer9 )d,Ethyl acetate is good solvent as log P lies within range of log p of many metabolites and ethyl acetate evaporates easily because of low boiling point and leaving behind solute. Ethyl acetate is immiscible with water due to polarity thats why this option cant be appropriate.
