The chemical equations that not only relate the mechanism but also outline the structure of the intermediate that forms in the rate determining step of the addition-elimination reaction of hexafluoro benzene and sodium methoxide are to be determined. Concept introduction: Nucleophilic aromatic substitution reactions involve the substitution of a leaving group by an upcoming nucleophile. The aromatic ring is itself act as a nucleophile, hence the ring undergoes this substitution only in the presence of a strong electron withdrawing so that it stabilized the negative charge on the ring.

Comparing two means. Horvat and co-workers used atomic absorption spectroscopy to determine the concentration of Hg in coal fly ash. Of particular interest to the authors was developing an appropriate procedure for digesting samples and releasing the Hg for analysis. As part of their study they tested several reagents for digesting samples. Their results using HNO3 and using a 1+3 mixture of HNO3 and HCl are shown here. All concentrations are given as ppb Hg sample. HNO3: 161, 165, 160, 167, 166 1+3 HNO3–HCl: 159, 145, 140, 147, 143, 156 Determine whether there is a significant difference between these methods at the 95% confidence interval.
