Interpretation: The most acidic hydrogen in the compound esmolol is to be labeled.
Concept introduction: The most acidic hydrogen
Answer to Problem 2.71P
The labeling of the most acidic hydrogen present in the compound esmolol is shown below.
Explanation of Solution
The most acidic hydrogen in the compound esmolol is shown as,
Figure 1
According to the structure of esmolol, there are three elements present in the compound to which protons are bonded. The acidity increases while moving left to right in the period due to an increase in the electronegativity of the elements. Thus, oxygen atom is located at the extreme right position in the periodic table and is highly electronegative than carbon and nitrogen. Thus, the proton that is attached to oxygen atom is the most acidic one as shown above.

- Using the Arrhenius equation, it is possible to establish the relationship between the rate constant (k) of a chemical reaction and the temperature (T), in Kelvin (K), the universal gas constant (R), the pre-exponential factor (A) and the activation energy (Ea). This equation is widely applied in studies of chemical kinetics, and is also widely used to determine the activation energy of reactions. In this context, the following graph shows the variation of the rate constant with the inverse of the absolute temperature, for a given chemical reaction that obeys the Arrhenius equation. Based on the analysis of this graph and the concepts acquired about the kinetics of chemical reactions, analyze the following statements: I. The activation energy (Ea) varies with the temperature of the system. II. The activation energy (Ea) varies with the concentration of the reactants. III. The rate constant (K) varies proportionally with temperature. IV.

Arsenic (As) is extremely toxic in its many forms and oxidation states. In nature, especially in groundwater, it is found in the form of arsenate (AsO ₄ ³ ⁻ ), which can be electrochemically reduced to As ⁰ and collected at the cathode of a coulometric cell. In this case, Potentiostatic Coulometry (at 25°C) was performed in an alkaline medium (pH = 7.5 throughout the analysis) to quantify the species. What potential (E) should have been selected/applied to perform the analysis, considering that this is an exhaustive electrolysis technique (until 99.99% of all AsO ₄ ³ ⁻ has been reduced to As ⁰ at the electrode, or n( final) = 0.01% n( initial )) and that the concentration of AsO ₄ ³ ⁻ found in the initial sample was 0.15 mmol/L ?
