wants to make a 1 liter solution of 0.5 M alanine at pH 2.6. The pKa of carboxylic acid is 2.34 and the pKa of α-amino group is 9.60. Use this information to answer questions 1-4. Which groups would be fully protonated or fully deprotonated at this pH?

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
