OVERVIEW

This course illustrates the basic principles of chemistry which are useful for the study of cultural heritage.

AIMS AND CONTENT

LEARNING OUTCOMES

The main target of the course is giving the students strong chemical foundations, stressing the general principles of basic subjects such as atomic and molecular structure, nomenclature, isomerism, physical and chemical properties, reactivity. On these foundations it will be based  a unitary, reasonably detailed and complete vision of the various features of the chemicals of greater specific interest, and of their use in preservation, consolidation and restoration of cultural heritage also through laboratory training  

AIMS AND LEARNING OUTCOMES

To enable students to understand structures and properties of the chemicals they are going to use in their future work.

To show that chemistry is a rational science, that all the subjects are connected together, so that the course is a unique reasoning developing from the first to the last lesson

TEACHING METHODS

Frontal lessons with slide projections and frequent interactions with the students

SYLLABUS/CONTENT

The Fundamental Laws of Nature. Molecular stability as determined by attractive and repulsuve intramolecular forces.

From atomic structure to the Periodic Table, to the various kinds of chemical bonds, to valence and to the various kinds of formulas. The 3D-structure of molecules and their simple rationale (VSEPR). Molecular models. Continuous and complete rotation around chemical bonds in open chains. Conformations. Possible rigid or semi-rigid sub-structures (double bonds, cycles) and possible cis/trans (Z/E) configurations. Symmetry planes. Chirality. Possible R/S confiurations. Molecules with one or more chirality centers. Constitutional or structural isomerism. Stereoisomerism: enantiomerism and diastereoisomerism.

Probabilistic character of our knowledge about the position of an electron in an atom. Atomic and molecular orbitals. The hybridation method. The resonance method. Electron delocalization and molecular stability. Resonance energy

Inorganic compounds.

Organic compounds. Aliphatic compounds. Functional groups and homologous series. Homocyclic compounds: alicyclic and aromatic ones. Heterocyclic compounds (aromatic or not aromatic).

Intermolecular forces and physical properties. Electric dipole moment, melting and boiling points, solubility in water and in organic solvents. Physical properties and isomerism. Colour. Coloured and colourless compounds for a human eye. Optical activity. Polarimeter..

Solutions. Acidity and basicity. pH..

CHEMISTRY FOR CULTURAL HERITAGE MODULE I

EXAMS

EXAM DESCRIPTION

After following the two modules of the course, students have to pass a unique exam, which will be an oral discussion of the various subjects of the both the modules.

ASSESSMENT METHODS

It is important that the students exhibits a real understanding of the matter, not only a by-heart study.
