Describing the adequate form of the reaction mechanisms and predicting the resulting compounds represent a challenge for students. A diagnostic evaluation was applied to a group of students enrolled in the industrial biochemistry engineering and food engineering programs who were taking an organic chemistry II class in the Unit of Teaching and Learning (UEA - Unidad de Enseñanza-Aprendizaje) to get well-acquainted with the basic concepts acquired in previous courses. The concepts that were evaluated were: Non-shared electrons, partial and formal charges, covalent and ionic bonds, homolitic and heterolytic break. The results of this research allowed to detect a deficient conceptual, procedural knowledge and a lack of systematization for the comprehension and development of the reaction mechanisms.

Palabras llave : Reaction mechanisms; basic concepts; procedural knowledge.
