Abstract
This study seeks to elucidate the fundamental principles underlying the hydration, hydrolysis, and enolization of β-diketones, aiming to enhance students’ comprehension of the link between fundamental chemical principles and the practical implications of keto–enol tautomerization and diketone-gem diol equilibrium in diverse chemical reactions. The research explores the hydration and hydrolysis kinetics of β-diketones using NMR and UV spectroscopy as well as the substituent effects on these kinetics and their influence on enolization. The insights gained from this study are valuable for students of chemistry, particularly those with an interest in the fundamental aspects of physical chemistry and the environmental aspects of organic chemistry. By establishing a clear link between theoretical insights and practical applications, this research contributes to the advancement of chemical education and provides students with a deeper understanding of the underlying chemical processes in real-world contexts.
期刊介绍:
The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
