Question on amines

IMAG2261.jpg hi, I am not sure why c will be the answer for q12 as the cooh group does react with Naoh..
Thanks

Forms salt of its conjugate BASE


Why would it not be the conjugate acid ? Since the cooh part is reacting.. Thanks

Read about conjugate acid-base pairs

I have just read this and my textbook carefully and I am still not sure on this. Is it because you can't refer the amino acid itself as its Conjugate acid??? I get that acid donates protons and bases accept protons . Thanks

NaOH would react with the acid group to form the sodium salt

when an acid group loses a proton, it forms a conjugate BASE.

The question says it reacts to form the conjugate ACID, that is not true.
