1) The conjugate acid form of an amine is ______. -protonated -deprotonated - ch

Question

1) The conjugate acid form of an amine is ______. -protonated -deprotonated - charged - both a and c are correct

2) If ethyl diethyl amine is placed in a very acidic solution with a pH well below its pKa, what will its structure be ?

3) If isopropyl amine is placed in a very basic solution with a pH well above its pKa, what is its primary form in solution ?

4) The conjugate base form of an amine is ______. -protonated -deprotonated - charged - both b and c are correct

5) At which of the following pH levels would you expect dipropyl amine (pKa = 11 ) to be the most soluble ? -pH=2 -pH=11 -pH=14 -pH has no effect on amine solubility

6) Which of the following is true with respect to the pKa of a functional group ?

- If the pH of the solution is equal to the pKa of the functional group, both the acid and base forms of the functional group will be found in the solution, at equal amounts.

-   If the pH of the solution is equal to the pKa of the functional group, the molecule will completely disintegrate.

- If the pH of the solution is higher than the pKa of the functional group, the functional group will exist predominately in the acid form.

- If the pH of the solution is lower than the pKa of the functional group, the functional group will exist predominately in the base form.
