Why are the carboxylic acid groups of the amino acids so much more acidic (pka~ 2) than a carboxylic acid such as acetic acid (p

ka=4.76)?

<span>The groups you mention are withdrawing electrons with inductive effect. Because there is no conjugation between the acids (pk-2 and pka 4.76), nitrogen makes it impossible to bind to the carboxyl group. Acids are affected in two ways, the first since the electron subtraction of charged oxygen molecules, and the second way by polarizing the O-H bond with carboxylic acid, this helps the protons to split easily.</span>

Answer:  Elements in Group 2

Explanation:  The periodic table was arranged by Dmitri Mendeleev specifically  around similarites in their chemical behaviors.  He found that as atomic number increases, at some point an element starts to react in a manner similar to a previous one.  When that happened, he would place the larger element under the smaller one, and eventually noticed a periodicity in the table.  Elements in a column (Groups) had similiar chemical properties.  We know today that these similarities are due to the electron configuration, and that these configurations repeat themselves.  He left gaps in the table when he could find an existing element with properties similar to others in that group.  I big leap of faith, but it worked.  Elements for those missing boxes were eventually discovered.
