Chemistry is the branch of science that focuses on the study of matter, its composition and properties, and the reactions that occur to form new compounds. Owing to its complexity, this branch of science is subdivided into biochemistry, and organic, inorganic, analytical, and physical chemistry. The idea that matter is made up of individual and indivisible parts (atomos) originated in ancient Greece and is attributed to the polymath Democritus. This idea has continued to evolve throughout history. The discovery of the fundamental particles of an atom, namely protons, neutrons, and electrons, was a prominent landmark. Recently, the planetary model of the atom has been replaced by the atomic orbital theory, which better describes electrons and chemical bonds.

In this course, the student will be introduced to atoms and its components, characteristics of chemical bonds, stereochemistry, electronegativity, acid-base reactions, organic chemistry, and chemistry topics related to the medical field, including biochemistry and pharmacology. For optimal comprehension, the student is expected to have a high-school–level understanding of chemistry and physics.

Chemistry is a fundamental prerequisite to understanding the concepts of biochemistry, which is a basic science in medical education integrated with molecular and cell biology. Pharmacology is the branch of chemistry that utilizes the concepts of chemistry for the development of drugs with better safety profiles.

Reaction of haloalkanes
By Zeem K. on 19. October 2021 for Sn1 Reaction – Haloalkanes

Very easy the explain ation was very good thanks alot sir

very good
By halima u. on 26. July 2021 for Chemistry: Introduction

it had good information but I just think it is too fast but overall good teaching.

Best teacher
By Rabiah A. on 05. June 2021 for Medical Chemistry

Great method of teaching... i have learnt a lot from this lecture and i like it very much

el numero cuantico spin es importante para cumplir la regla de exclusión, la regla de Hund (emparejamiento)
By Claudia A. on 02. March 2021 for Introduction – Quantum Numbers

Por que explicó detalladamente y con ejemplos la importancia del principio de exclusión de Pauli y que para que se cumpla en el orbital S, debemos considerar al numero cuantico spin
