Question

Use the Brønsted-Lowry definitions to identify the first compound in each equation as an acid or a base. (Hint: What is produced by the reaction?) (CH3)2NH+H₂O→(CH3)2NH+2+OH⁻

1) acid
2) base

Answer 1

The first compound in the reaction, (CH3)2NH, functions as a Brønsted-Lowry base because it accepts a proton from water, which in this case acts as the Brønsted-Lowry acid. Option 1

Step-by-step explanation:

According to the Brønsted-Lowry definitions, an acid is a compound that donates a proton (H+) to another compound, while a base is a compound that accepts a proton. In the given reaction (CH3)2NH+H2O→(CH3)2NH2++OH−, the first compound ((CH3)2NH) is acting as a base because it is accepting a proton from water (H2O), which is acting as an acid, to form the product (CH3)2NH2+.

The byproduct of this reaction is the hydroxide ion (OH−), which confirms that the first compound accepted a proton, due to the increase in the hydroxide ion concentration. Option 1
