I have no idea how to answer this chain question. Please walk me through everything I should know and do so that I can understand it thoroughly.

Part II. 35 points. Match the description with the letter of the appropriate compound (each used once) OB NH2 A strong, non-nucleophilic base A strong nucleophile that is only a moderate base AL N D Hac-ci A strong base that is also a strong nucleophile A nonpolar, aprotic solvent E A moderate nucleophile that is only a moderate base a NH3 A polar, protic solvent DFI A polar, aprotic solvent

Explanation / Answer

D is strong non nucleophilic base. The presence of negative charge or unsatisfied valency make it a strong base. This charged species cannot be stabilised by resonance. Presence of bulky methyl group in the ring makes it non nucleophilic

A is strong nucleophile but a moderate base. This because of stabilisation of negative charge by resonance.

B is strong nucleophile and strong base. No stabilisation of charge as well as no bulky group to prevent nucleophilicity.

F is a nonpolar hydrocarbon solvent and also aprotic since there are no labile H+

G is a moderate nucleophile as well as moderate base.

E is a polar protic solvent due to the Presence of electronegative oxygen and labile proton.

C is polar due to presence of nitrogen but aprotic. There is no labile H+
