PHAR1911 Chemistry Notes

Description

Topics: - Atomic structure and isotopes (including hydrogen isotopes, PET scans). - Bohr and Schrödinger models of the atom. - Quantum numbers, orbitals, Pauli Exclusion Principle. - Periodic trends (atomic radius, ionisation energy, electronegativity) - Elements in the body (Na⁺, K⁺, Mg²⁺, Ca²⁺, transition metals). - Chemical bonding: ionic, covalent, metallic. - Molecular structures, VSEPR theory, Lewis dot diagrams, formal charge. - Resonance structures and stability. - Intermolecular forces (dispersion, dipole–dipole, hydrogen bonding). - Applications in biology/pharmacology (, morphine, DNA bonding). - Thermodynamic concepts: temperature, melting and boiling points. - Organic chemistry basics: hybridisation (sp, sp², sp³), sigma and pi bonds. - Isomerism: structural isomers, cis/trans (E/Z) isomers, chirality/enantiomer Covers week1-13
