2:35 PM eoooo AT&T; 53% Expert Q&A; Done help solve #4 and #5 please Which the following is true the strength of a nucleophile? Naleopharity may not parallel basicity. Negatively charged are always more reactive than their conjugate acids. udeophies will occur. d The greater the strength of a the faster an S2 reaction nuceophile, Stroni bases are always good nucleophies el None of these answer choices are correct. Which of the following statements is (are) true ofs..l reactions of allkyl halidesin general? A) The rate of an reaction depends on the concentration of the nucleophile. of an reaction depends on the concentration of the alkyl halide. Sul reactions of alkyl halides occur faster in polar aprotic solvents (compared to protic solvents). D) Polar, protic favor snl reactions because they solvate the nucleophile E reactions occur in pr step via a carbocation transition state.

Explanation / Answer

3) option C

the elimination of HBr froma an alkyl halide in presence of EtONa /EtOH by E1 Or E2 generally give the trans / E- alkene.

4) Option D

Strong bases are NOT ALWAYS strong nucleophiles.

for example bulky bases like t-butoxide which is a very strong base is not a very good nucleophile due to its bigger size.

5) OPtions B and D are the correct statements.

SN1 is a two step reaction, whose rate depends only on concentration of alkyl halide and is favored in polar protic solvents.
