Question

What is the equation for ethyl 4-aminobenzoate + HCl and then that + NaOH?

Answer 1

Concepts and reason

According to Bronsted-Lowry acid base theory, bases can deprotonate the acid. So acids are defined as proton acceptors and bases are proton donors.

Fundamentals

Base: The compounds, which readily accept the proton or having atoms with lone pair of electrons, are base

Acid: the compounds, which readily donate the proton or have an empty orbital to accept lone pair of electrons.

Given reactants are ethyl-4-aminobenzoate and ${\rm{HCl}}$ .

In 4-aminobenzoate two functional groups are present; one is ester group and the other is amine group.

This compound is soluble in acid solutions because of the basic nature of 4-aminobenzoate due to the presence amine functional group.

Reaction between ethyl-4-aminpobenzoate and ${\rm{HCl}}$

It is also possible,

The salt formed in step1 ethyl-4-ammoniumbenzoate salt act as acid and reacts with strong base ${\rm{NaOH}}$ leads to ethyl-4-aminobenzoate.

Ans:

Ethyl-4-aminobenzoate+ ${\rm{HCl}}$ and then that+ ${\rm{NaOH}}$ ?
