Chapter 1.5, Problem 11ATS
Interpretation Introduction

Interpretation: For the given set of compounds the location of the partial charges that results due to inductive effect should be identified.

Concept Introduction: The nature of the bond depends on the electronegativity values of the shared electron pair of the involved atoms.

Electronegativity is the important chemical property of the elements in the periodic table.  It is the tendency of the atoms to attract electrons towards it.

If the difference in electronegativity is between 0.5 and 1.7, a bond between two different electronegative atoms becomes polar.  Most electronegative atoms get partial negative charge because they attract electrons from least electronegative atom towards it.  The least electronegative atoms get partial positive charge because it loses electrons towards most electronegative atoms.

The process of the attraction of electrons from electron-donating atoms (less electronegative atoms) towards electron-withdrawing atoms (most electronegative atoms) is called induction.  It can be represented by the following arrow:

Here, chlorine atom has more electronegative than carbon atom.  Chlorine attracts electrons towards it.  This difference in electron density is called inductive effect.  It can be shown by Greek symbol delta ( δ ) as follows:

The partial positive charged region is easily attracted by the anions in a compound.

To find: Identification of two carbon atoms that are most likely to be attacked by an anion, such as hydroxide ion in a given compound

The data for the potential difference of a battery and its temperature are given in the table. Calculate the entropy change in J mol-1 K-1 (indicate the formulas used).Data: F = 96485 C mol-1
In a cell, the change in entropy (AS) can be calculated from the slope of the E° vs 1/T graph. The slope is equal to -AS/R, where R is the gas constant. Is this correct?
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. The value of the…
