Study Notes

Bonding Types

Non-polar bonds occur even with different atoms, often found in regions rich in carbon and hydrogen without electronegative atoms (N, O, F).
Coordinate covalent bonding involves the sharing of electrons where one atom (ligand) donates a lone pair to bond with a transition metal ion, often seen in biological contexts.
Transition metals commonly bond with ligands that possess lone pairs, essential for molecular structures like hemoglobin.

Covalent vs Ionic Bonding

Covalent bonding involves the sharing of electrons between non-metals, while ionic bonding typically involves metals and non-metals forming cations and anions.
Polar covalent bonds arise from differences in electronegativity, leading to partial positive and negative charges. Fluorine is the most electronegative element.
Non-polar covalent bonds occur between identical atoms or similar non-metals, such as carbon and hydrogen.

Molecular vs Ionic Compounds

Molecular compounds consist of non-metals and can exist as individual molecules (e.g., carbon dioxide), while ionic compounds form large crystalline structures and do not exist as independent molecules.
Sodium chloride (NaCl) is an example of an ionic compound, while carbon dioxide is a molecular compound.

Intermolecular Forces

Three main types of intermolecular forces relevant to biological contexts: hydrogen bonding, dipole-dipole interactions, and London dispersion forces.
Hydrogen bonds are strong dipole-dipole interactions involving hydrogen covalently bonded to either fluorine, oxygen, or nitrogen.
Dipole-dipole forces occur between polar molecules due to interactions between their partial positive and negative charges, weaker than both ionic and covalent bonds.

Biological Significance

Hydrogen bonding plays a crucial role in stabilizing the structure of proteins and nucleic acids, such as DNA, where it holds the two strands of the helix together.
Water, essential for life, exhibits extensive hydrogen bonding due to its hydroxyl (OH) groups, facilitating various biochemical processes.
Understanding these bonding types and intermolecular forces is fundamental to grasping the chemical behavior of biological molecules.
