Question

What am I doing wrong? I think the proton on the amine is more acidic and the conjugate acid seems to be more acidic than the acid which doesn't make sense for the Keq value.

Putting it all together = acid-base reactions. For each reaction below, two protons are indicated. Choose the CORRECT
acidic proton that will make the reaction go to the right as written. If the following reaction does NOT go to the right as
written draw an X instead of products (blank answers will not be counted for credit). Once you have determined the
correct proton, complete the following reactions using the appropriate curved arrows to show the flow of electrons
pairs in each reaction. Calculate the Keg for each reaction. Write the pka values under each acid, so we can evaluate
your progress better and give partial credit. Finally, label the acid (A), base (B), conjugate acid (CA) and base (CB)
correctly.

Expert Solution

Step 1

Acidity of a hydrogen atom depends on the adjacent hetero atom to which the hydrogen atom is attached.

More electronegative the heteroatom, more acidic the attached hydrogen atom will be.

This can be explained in terms of polarity difference.

Acidity can be defined as the ability of a compound to release a proton. In other words, the hydrogen atom that can easily be removed as H⁺ is termed as an acidic proton.

Now, if a hydrogen atom is attached with a heteroatom A, then the acidity of the hydrogen will depend upon the electronegativity of A.

Higher the polarity difference of $H - A$ bond, easier for us to remove the hydrogen and hence, more acidic the hydrogen will be.

Finally, we can say more electronegative the atom A is, more polar the $H - A$ will be and more acidic the associated hydrogen will be.
