An analust is trying to separate a mixture containing the following four organic compounds

She dissolved the mixture in ether and treated the solution with aqueous `NaOH` solution and finally separated the two fractions: Fraction-I (ether) and Fraction-II (aqueous). Later she acidified Fraction-1 and was able to distill the organic compound(s) into ether to obtain third fraction, Fraction-III. Fraction-III was then treated with aqueous `NaHCO_(3)` and the two layers, ether layer (Fraction-IV) and aqueous layer (Fraction-V) were separated. Also Fraction-I was treated with aqueous `HCl` solution and the two layers, other (Fraction-VI) and aquores layer (Fraction-VII) were seperated. Answer the following three questions based on the above information.
Fraction-V on acidification followed by distillation will give
