AGUILERA MARTINEZ, Leidy Angélica  y  GARAY, Fredy Ramón Garay. Organic chemistry structuration from dual and unitary theories: a Kuhnian look. Educ. quím [online]. 2014, vol.25, n.2, pp.148-153. ISSN 0187-893X.

Reflections on how scientific knowledge and chemical development has been formulated and constructed, have led to an in-depth review and analysis about the nature of the theories, laws, models and concepts, which can be termed as the "conceptual structure of chemistry." This work focuses on the review and analysis of both the dual theory of J. J. Berzelius theory, as well as the unitary one by A. L. Laurent, as potential structural axes of Organic Chemistry. In this sense, we try to reveal the confrontation of positions of empirical scientific communities representative of nineteenth century. The unitary theory -or antidualistic- has consolidated today as theory, to achieve assertive explaining of chemical phenomena, which has been not possible with the dual theory. Such revision of the two structural theories was made from an analytical perspective, which included the theoretical assumptions of Thomas Kuhn on the development of scientific knowledge. This account of scientific conceptions and preconceptions own of its time, on the "effective" matter composition, with an approach to different concepts of "weight" in the construction of such theories, which will hopefully reflect the historical-epistemological discussion on the chemical nature of scientific knowledge.

Palabras llave : chemical nature of scientific knowledge; unitary theory; dual theory.
