Question
Chapter 2, Problem 73P
Interpretation Introduction
(a)
Interpretation: The given reaction is to be classified as either a proton transfer reaction or a reaction of electrophile and nucleophile. The movement of electrons is to be shown by curved arrows.
Concept introduction: Lewis acid accepts an electron pair. It acts as an electrophile Lewis base donates an electron pair. It acts as nucleophile. Conjugate base is formed by the loss of a proton from an acid while conjugate acid is formed by the gain of electron by a base.

- 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.arrow_forwardComparison of experimental data to “known” value.
