8. a) Make a list of good nucleophile vs poor nucleophiles.b) Draw the structure of the following solvents and label them aspolar/non-polar/polar-protic/polar aprotic, and indicate which reaction, they would be suited for (SN1, SN2 or neither)-hexane-acetone-water-Dimethyl formamide, DMF-Dimethyl sulfoxide, DMSO-benzene-acetic acid-Tetrahydrofuran, THF-ethyl acetateExplain why certain solvents are appropriate for SN2 compared to SN1 reaction
