The three units that must be present in a nucleotide have to be found. Concept Introduction: Concept of Nucleic acids and Nucleotides: • Nucleic acids are biopolymers that are essential to all forms of life. • The nucleic acid is composed of nucleotides . • The nucleotides are monomers that form the nucleic acid. • Each monomeric unit of nucleotide are made of three components such as 5-carbon sugar, a phosphate group and a nitrogenous base. • The 5-carbon sugar can be ribose or deoxyribose sugar. • If the 5-carbon sugar is a ribose unit , then the overall nucleic acid is known as Ribonucleic Acid which is abbreviated as RNA . • If the 5-carbon sugar is a deoxyribose unit , then the overall nucleic acid is known as Deoxyribonucleic Acid which is abbreviated as DNA .

The three units that must be present in a nucleotide have to be found.

Concept Introduction:

Concept of Nucleic acids and Nucleotides:

• Nucleic acids are biopolymers that are essential to all forms of life.

• The nucleic acid is composed of nucleotides.

• The nucleotides are monomers that form the nucleic acid.

• Each monomeric unit of nucleotide are made of three components such as 5-carbon sugar, a phosphate group and a nitrogenous base.

• The 5-carbon sugar can be ribose or deoxyribose sugar.

• If the 5-carbon sugar is a ribose unit, then the overall nucleic acid is known as Ribonucleic Acid which is abbreviated as RNA.

• If the 5-carbon sugar is a deoxyribose unit, then the overall nucleic acid is known as Deoxyribonucleic Acid which is abbreviated as DNA.

(b)

Interpretation Introduction

Interpretation:

The type of bonding that holds the three units of nucleotide has to be found.

Concept Introduction:

Covalent bond:

Covalent bond is a chemical bond that is formed by mutual sharing of electrons between atoms. The shared electron pairs are known as bonded electron pairs. The formation of a covalent bond stabilizes the attractive and repulsive forces between atoms that involve in the bonding.

-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
