Study Notes
BSc Second Semester - Chemistry
The second semester of a Bachelor of Science degree is typically focused on inorganic chemistry, organic chemistry, and physical chemistry. These branches of chemistry will form the foundation for more specialized courses later in your studies. Let's delve into each of these areas.
Inorganic Chemistry
Inorganic chemistry involves the study of elements and their compounds other than those of hydrocarbons (i.e., carbon compounds). This branch deals with various structures such as ionic solids, molecular solids, metals, metal complexes, etc.. Some of the concepts you might explore during this period include coordination number and coordination geometry, trends in properties among transition metals, precipitation reactions, and stoichiometry.
Coordination Number and Geometry
When discussing coordination spheres, we often refer to the number of ligands around a central atom as the coordination number (CN). For example, if there are three atoms bonded in a plane around another atom, that would be trigonal planar (triangular) coordination geometry. Similarly, tetrahedral refers to four ligands equidistant from the central atom, octahedral refers to six ligands, and so on.
Trends Among Transition Metals
Transition metals generally have a series of oxidation states in which they can exist. As you progress through your studies, you may learn how these variations arise due to the presence of d orbitals in the outermost energy level of most transition metal atoms.
Precipitation Reactions
Precipitation reactions occur when two solutions react to give an insoluble solid called a precipitate, which separates out. Understanding these types of reactions helps you predict whether a reaction will produce a precipitate based on the solubility rules for different ions and compounds.
Stoichiometry
Stoichiometry is concerned with determining quantitative information about chemical reactions, including balancing equations, determining limiting reagents, and calculating mass relationships between reactants and products.
Organic Chemistry
Organic chemistry focuses on the structure, synthesis, and reactions of organic compounds made up primarily of carbon bonds. During your study of organic chemistry, you may delve into the following topics:
Synthetic Organic Chemistry
Synthetic organic chemists create new compounds by combining existing ones together with different pathways and strategies. These strategies include substitution reactions, eliminations, additions, and rearrangements.
Stereochemistry
Stereoisomers are molecules that have the same molecular formula but differ only in the arrangement of their atoms in space. Understanding stereochemistry allows you to describe and predict the differences in shape, stability, and reactivity of these molecules relative to one another.
Physical Chemistry
Physical chemistry explores the macroscopic behavior of matter and its interactions with energy at both microscopic and macroscopic scales. It encompasses several key areas: thermodynamics, kinetics, electrochemistry, and statistical mechanics.
Thermodynamics
Thermodynamics provides principles to understand changes in systems, such as the transfer of heat, work, or mass between them. Key concepts in thermodynamics include internal energy, enthalpy, entropy, free energy, equilibrium, phases, and phase diagrams.
Kinetics
Kinetics deals with the rates of chemical processes and the factors that influence them, as well as the mechanism behind these reactions. The study of kinetics includes both unimolecular and bimolecular rate laws, the effects of concentration, temperature, and catalysts on reaction rates, and collision theory.
Electrochemistry
Electrochemistry combines aspects of chemistry and physics, using electrical methods to drive chemical reactions. This field involves understanding redox reactions, cell potentials, half-reactions, and reaction mechanisms.
Statistical Mechanics
Statistical mechanics describes how particles move and interact in a macroscopic system. It involves applying probability distributions and statistical theories to explain phenomena observed at large scales.
These subtopics offer just a glimpse into what you can expect to learn during your second semester studying chemistry as part of a Bachelor of Science program. Each concept builds upon previous knowledge, preparing you for further specialization within your chosen area of study.
