Question
Chapter 4.10, Problem 4.22KCP
Interpretation Introduction
Interpretation:
For the compound methyl lithium (
Concept introduction:
Covalent bonds are formed by sharing of electrons between atoms.
The polarity of a bond is arises due to the difference in electronegativity of atoms present in that bonding.
The direction of net polarity is the resultant vector of the vectors drawn for dipole moment of each bonds.

Mixtures of amino acids can be analyzed by first separating the mixture into its components through ionexchange chromatography. Amino acids placed on a cation-exchange resin containing sulfonate ( -SO3-) groups flow down the column at different rates because of two factors that influence their movement: (1) ionic attraction between the sulfonate residues on the column and positively charged functional groups on the amino acids, and (2) aggregation of nonpolar amino acid side chains with the hydrophobic backbone of the polystyrene resin. For each pair of amino acids listed, determine which will be eluted first from the cation-exchange column by a pH 7.0 buffer. (a) Aspartate and lysine (b) Arginine and methionine(c) Glutamate and valine (d) Glycine and leucine (e) Serine and alanine
Mixtures of amino acids can be analyzed by first separating the mixture into its components through ion‑exchange chromatography.
Amino acids placed on a cation‑exchange resin containing sulfonate (−SO−3)(−SO3−) groups flow down the column at different rates because of two factors that influence their movement: (1) ionic attraction between the sulfonate residues on the column and positively charged functional groups on the amino acids, and (2) aggregation of nonpolar amino acid side chains with the hydrophobic backbone of the polystyrene resin.
Note that the ionic attraction is more important than hydrophobicity for this column media.
For each pair of amino acids, identify which will be eluted first from a cation‑exchange column using a pH 7.0pH 7.0 buffer.
