Question

What is the conjugate acid of the Brønsted-Lowry base, CH₃NH₂?

Answer 1

Recall that a Bronsted-Lowry base is defined to accept protons.

To find the Conjugate pair, you should assign the acid or base in an hydrolysis acid-base reaction. You should do it with the amphoteric water, \(H_2O\)

\(\text{CH}_3\text{NH}_2+\text{H}_2\text{O} ⇌\text{CH}_3 \text{NH}_{3}^++\text{OH}^- \)

The proton from water was donated to CH3NH2 to make CH3NH3 +, the CA
