a) p-Nitroaniline, p-aminobenzaldehyde, p-bromoaniline
Interpretation:
The compounds p-nitroaniline, p-aminobenzaldehyde and p-bromoaniline are to be arranged in the increasing order of their basicity.
Concept introduction:
b) p-Chloroaniline, p-aminoacetophenone, p-methylaniline
Interpretation:
The compounds p-chloroaniline, p-aminoacetophenone and p-methylaniline are to be arranged in the increasing order of their basicity.
Concept introduction:
Amines are basic as they can donate the lone pair if electrons on the N atom. Generally aryl amines are less basic than alkyl amines. An electron withdrawing substituent present on the aromatic ring reduces the base strength while an electron releasing substituent present on the aromatic ring enhances the base strength.
c) p-(trifluoromethyl)aniline, p-methylaniline, p-(fluoromethyl)aniline
Interpretation:
The compounds p-(trifluoromethyl)aniline, p-methylaniline and p-(fluoromethyl) aniline are to be arranged in the increasing order of their basicity.

- How to solvearrow_forwardIndicate the concentration and ionic strength ranges to which the Debye-Huckel equation can be applied. And the Davies equation?arrow_forwardIf the ionic strength (I) of a solution is very low, the Debye-Huckel equation is used. If I is higher, the Davies equation is used. What is the correct value for I to use one or the other?arrow_forward
- In both the Debye-Huckel equation and the Davies equation, there is a constant A. I see that sometimes it appears as 0.51 and other times as 1.02. Explain why one or the other value is used.arrow_forwardThe two equations are forms of the Davies equation, used in thermodynamics for activity coefficients: ال log Y₁ = -Az² - 0,31 log = Az² - 0,31 1 + √Ĩ 1 + √√ k These equations are consistent and imply that Yi = Is this last equation correct? karrow_forwardThe two equations are forms of the Davies equation, used in thermodynamics for activity coefficients: ال log Y₁ = -Az² - 0,31 log = Az² - 0,31 1 + √Ĩ 1 + √√ k These equations are consistent and imply that Yi = Is this last equation correct? karrow_forward
- For the Davies equation, both expressions are correct: log Y₁ = -Az² √i - 0,31 1 + √ k log- = Az - 0,31 k 1 + √Ĩarrow_forwardk In Davies' equation log y₁ = log- log y₁ = log | = -Az² + ✓// k A is a constant that always equals 1.02. Correct? - 0,31arrow_forwardIndicate whether the equality is true Yi How is it obtained? k%arrow_forward
- Indicate the relationship between the activity coefficient YA and the rate constant of a bimolecular reaction in solution k and the rate constant at infinite dilution ko.arrow_forwardDescribe the saline effect that occurs in solutions.arrow_forwardBriefly explain what the infinite dilution rate constant (k∞) consists of.arrow_forward
