AIMS AND CONTENT

LEARNING OUTCOMES

The students will be provided with the fundamental knowledge of organic chemistry and of reactivity of monofunctional substances. First they will be taught how to write correctly Lewis and Kekulé formulas and be introduced to important concepts regarding the chemical bonds, resonance, organic acids and bases, diversity and shape of molecules (with particular emphasis on stereochemistry), nomenclature of the main classes of compounds (including aromatic and heterocyclic substances). The main objective will be to make the students apprehend the main organic reactions (electrophilic or nucleophilic additions to double and triple C=C bonds and to double C=O bonds, electrophilic aromatic substitutions, acyl, aliphatic and aromatic nucleophilic substitutions, formation of C-C and C=C bonds, redox reactions, radical reactions) and to comprehend synthetic applications and thermodynamic, kinetic and experimental aspects.

PREREQUISITES

The fundamental concepts of General Chemistry acquired during the course of General and Inorganic Chemistry in the first semester

TEACHING METHODS

Traditional lessons in the classroom (64 hours). The solutions of problems will be treated in additional and optional tutoring hours. The attendance is not compulsory but, for statistical means, it wil be anyway monitored.

EXAMS

EXAM DESCRIPTION

The students who want to be submitted to the exam must registrate at least 48 hours in advance on https://servizionline.unige.it/studenti/esami/prenotazione

The exam will be essentially oral. However, it will be preceded, on the same day, by a written exam, whose aim is just to filter off the unprepared students in order to avoid useless loss of time for both sides. Therefore the written exam will not involve solution of problems, it will be relatively easy, and onlt these four outcomes will be communicated few hours after its end: excellent, good, sufficient and not sufficient. Only the students who have gained the first three grades will be admitted to the oral exam. The grade obtained during the written exam will not count for the final grade, apart from the fact that the maximum available grade for those judged "sufficient" will be 26. Even the students who have got "excellent" may eventually fail the oral exam.

The oral exam will involve 3 questions. The first one will be quite general and will be taken from a list that will be made public, during the course, through the "aulaweb" service. The second and third will be more specific. The relative weight of the three questions will be, approximately, 50%, 25%, 25%. When students who have got "excellent" in the wrtten exam, answers very well to the first question, the commission may decide to stop the exam (with a grade of 30) or to pose a more difficult question in order to judge if the student is worth the "cum laude".

During the oral exam the student must demonstrate to have reached the learning outcomes, both orally and (most importantly) writing formulas, chemical equations, mechanisms.
In case of students who have certified a "specific learning disease" (DSA) the commission may decide to go directly thrpough the oral exam where the student will be given enough time to understand the questions and answer to them. Requests of these aids must be presented not directly to the professor, but to the reference persons for DSA at the School of Science.

When the commission will judge that the learning oucomes have not been reached, the students willbe invited to repeat the exam in one of the subsequent dates.

When the commission have decided for a positive grade, the student may ask to refuse ot and repeat the exam. However the commission will decide whether to accept or not this refusal. In any case the request of refusal must be presented at once, and students are not allowed to change their minds later. If, later,the students repeats the exam and obtain an inferior grade, he/she can not ask to receive the grade that he/she had preiously refused.

 

ASSESSMENT METHODS

The oral exam is always carried out by two teachers with at least 5 years of experience and will last at least 30 minutes. In this way, taking into account also the preliminary written exam, the commission is definitely able to verify with high accuracy if the student has reached or not the learning outcomes.

During the oral exam the student must demonstrate to have reached the learning outcomes, both orally and (most importantly) writing formulas, chemical equations, mechanisms.

When the commission will judge that the learning oucomes have not been reached, the students willbe invited to repeat the exam in one of the subsequent dates.
