Chapter 13, Problem 9Q

(a)

Interpretation Introduction

Interpretation: From the given figures of comparison, the two functional groups that react to form a polymer similar to DNA have to be circled.

Concept Introduction:

DNA:

DNA is a self-replicating genetic material that is present in all living organisms. It carries genetic information from one generation to the several successive generations. Basically it is a biopolymer of nucleotides which are monomeric units and each monomeric unit has three major components such as a deoxyribose sugar unit, a phosphate group and a nitrogen-containing base.

(b)

Interpretation Introduction

Interpretation:

The sugar unit that is given in the figure of question 8 is a ribose sugar rather than a deoxyribose sugar. A polymer that is formed from this nucleotide has to be named.

Concept Introduction:

RNA:

RNA is a polymeric molecule. It is an essential molecule that plays a major biological role in coding, decoding, regulation and expression of genes. Basically it is a biopolymer of nucleotides which are monomeric units and each monomeric unit has three major components such as a ribose sugar unit, a phosphate group and a nitrogen-containing base.

-Page: 8 nsition metal ions have high-spin aqua complexes except one: [Co(HO)₁]". What is the d-configuration, oxidation state of the metal in [Co(H:O))"? Name and draw the geometry of [Co(H2O)]? b) Draw energy diagrams showing the splitting of the five d orbitals of Co for the two possible electron configurations of [Co(H2O)]: Knowing that A = 16 750 cm and Пl. = 21 000 cm, calculate the configuration energy (.e., balance or ligand-field stabilization energy and pairing energy) for both low spin and high spin configurations of [Co(H2O)]. Which configuration seems more stable at this point of the analysis? (Note that 349.76 cm = 1 kJ/mol) Exchange energy (IT) was not taken into account in part (d), but it plays a role. Assuming exchange an occur within t29 and within eg (but not between tz, and ea), how many exchanges are possible in the low in configuration vs in the high spin configuration? What can you say about the importance of exchange energy 07
