Question

Many organic molecules act as acids and bases and can exist in an acid or base form. For each molecule, match the following acid or base with its' conjugate base or acid

1.)

CH₃NH₂

2.)

CH₃CH₂O^-

3.)

CH₃CH₂N(CH₃)₃⁺

4.)

CH₃CH₂OCH₃

5.)

(CH3)3NH+

A.	CH3NH3+
B.	(CH3)2NH2+
C.	CH3CH2O-
D.	CH3CH2OH
E.	(CH3)3N
F.	CH3CH2OOH
G.	None of theses.

Answer 1

To explain it better and you understand this better, My answer would be done in form of reaction. I'll do the reaction of all these compounds with water so you may see the conjugate acid or base:

1. CH₃NH₂ + H₂O <----------> CH₃NH₃⁺ + OH^-   A)

2. CH₃CH₂O^- + H₂O <---------> CH₃CH₂OH + OH^-   D)

3. CH₃CH₂N(CH₃)₃⁺ + H₂O <---------> CH₃CH₂⁺ + N(CH₃)₃ + H₃O⁺   E)

4. CH₃CH₂OCH₃ + H₂O <---------> CH₃CH₂OHCH₃⁺ + OH^-   G)

5. (CH₃)₃NH⁺ + H₂O <---------> (CH₃)₃N + H₃O⁺   E)

Hope this helps. Tell me if you need something else or something to be fixed.
