Question

question 5
if we treat benzocaine with hcl, what will happen?
askcuddy
it will get protonated
nothing
it will get deprotonated

Explanation:

Benzocaine has an amine group (\(-\text{NH}_2\)). \( \text{HCl}\) is an acid. In an acid - base reaction, the amine group in benzocaine can accept a proton (\(\text{H}^+\)) from \( \text{HCl}\). Protonation of the amine group (\(-\text{NH}_2+\text{H}^+\to-\text{NH}_3^+\)) occurs. Deprotonation would involve losing a proton (not the case here as \( \text{HCl}\) donates protons). And "nothing" is incorrect because there is a reactive group (amine) in benzocaine that can react with \( \text{HCl}\).

Answer:

it will get protonated
