AIMS AND CONTENT
LEARNING OUTCOMES
The teaching aims to illustrate simple applications of modern Quantum Chemistry to Organic Chemistry; in particular, to develop concepts and describe the application of qualitative and semiquantitative methods for describing the reactivity of organic molecules.
AIMS AND LEARNING OUTCOMES
In particular, the teaching of Organic Physical Chemistry you will find the elements to rationalize organic reactivity through symmetry properties of the reactants and / or products (WoodwardHoffmann rules) or from the analysis of the reaction profile (theory of frontier orbitals). Furthermore (depending on the time available) the basic elements of quantum mechanics will be provided, aimed at describing the most used abinitio and semiempirical methods for the calculation of molecular properties.
The student will acquire:
 the ability to identify the different types of pericyclic reactions
 knowledge of the classical and generalized WoodwardHoffmann rules;
 the ability to apply these rules in the prediction of the products of a pericyclic reaction;
 knowledge of the KlopmanSalem equation and its limits of applicability;
 the ability to apply the KlopmanSalem equation to a varied series of chemical reactions in order to predict their products or discuss their experimental observations in a semiquantitative way.
 the ability to correlate the KlopmanSalem equation to different predictive models of organic reactivity.
 the knowledge and the ability to apply an effective Hamiltonian model to the calculation of the molecular energies and orbitals of a conjugated organic molecule.
PREREQUISITES
A review of the subjects related to the teaching of Physical Chemistry 3 of the threeyear course may be useful, with particular reference to the method: variational, perturbative and to the LCAO theory. Also are required the knoweledge of the Mathematical and Physics teachings of the first years.
TEACHING METHODS
The teaching corresponds to 6 CFU equivalent to 150 hours of "effective" commitment by the student and is divided as follows: 48 hours of lectures and 102 hours of personal study (the latter include iterative teaching activities  selfevaluation quizzes, discussion forums , indepth material  which can be chosen independently by the student). The course it is held in Italian language.
In this context, at the discretion of the teacher, selftests (openended, multiplechoice questions or numerical exercises) and / or iterative or noniterative auxiliary materials are uploaded on the aulaweb page, in order to facilitate the individual study of the students.

EXAMS
EXAM DESCRIPTION
The oral examination is conducted by two tenured professors and has a duration of at least 45 minutes.
Warning! In variation to the normal practice adopted in the CCS, for this course (for the purpose of better organizational management of the exam), enrollment must be made 5 working days before the exam date.
The exam consists of three blocks of two questions (relating to the Conservation of Symmetry including related topics and to the Theory of Frontier Orbitals including related topics,respectively) of increasing difficulty aimed at verifying the candidate's knowledge, skills and abilities.
The first block, knowledge check, corresponds to 18 points out of 30.
The second block, skills check, corresponds to 8 points out of 30.
The third block, abilities check, corresponds to 4 points out of 30.
ASSESSMENT METHODS
The oral exam is aimed at verifying the achievement of an adequate level of knowledge of the topics developed / discussed during the lessons and the ability to use the correct terminology combined with the consistency of exposure of the concepts and methodologies described in the teaching.
In particular, through a series of questions of increasing difficulty, the candidate's ability to apply the theory of Conservation of Symmetry and the theory of Frontier Orbitals will be assessed in the description of the reactivity properties of molecules in relation to specific model cases and / or exercises. As indicated in the exam descriptions, these are three blocks of questions; the first aimed at verifying the acquisition of the notional contents of the course (knowledge), the second aimed at verifying the ability to apply these contents to model exercises (skills) and finally the third aimed at verifying the candidate's ability to solve exercises of a general nature, relating to molecular reactivity, applying the knowledge and skills acquired (abilities).
Overcoming the first block allows the candidate to acquire a maximum of 18 out of 30 points (therefore a maximum score of 18/30). If the score obtained in this phase is such as not to guarantee sufficiency as a final grade, the commission will invite the candidate to withdraw and deepen the study of the subject also making use of further explanations by the teacher before repeating the exam.
Overcoming the second block allows the candidate to acquire a maximum of 8 out of 30 points (therefore, also considering the previous block, with a maximum score of 26/30).
Overcoming the third block allows the candidate to acquire a maximum of 4 out of 30 points (therefore, also considering the previous block, with a maximum score of 30/30).
The candidate has the right to decide whether to face the two blocks following the first one or to stop and obtain the total score obtained as a vote.
Examples of a possible exam course:
Case (a) the candidate does not fully pass the first block. The score acquired and the progress of the exam is such as to make the commission believe that the minimum score of 18/30 cannot be acquired; the candidate is invited to withdraw.
Case (b) the candidate fully passes the first block, acquires the score of 18/30. He decides to move on to the second block which does not fully pass acquiring a vote between 1826 / 30 and decides not to continue. The score obtained will correspond to the final mark.
Case (c) the candidate fully passes the first block, acquires the score of 18/30. He decides to move on to the second block which he does not pass fully, acquiring a score between 1826 / 30 and decides to want to move on to the third block. In this case you will be able to acquire a maximum of 4 out of 30 points, and the total score obtained will correspond to the final mark.
Note: if the candidate decides not to follow the commission's invitation to withdraw (if the need arises) and the final mark obtained is insufficient, it will be registered.
