This course unit detail provides the framework for delivery in 22/23 and may be subject to change due to any additional Covid-19 impact.
This course is specifically designed for Biology students who have not taken Chemistry at A level or equivalent. It aims to provide a basic introduction to the fundamental principles and concepts of chemistry that are relevant to biologists.
CHEM10111 aims to provide a description of: atomic structure and molecular structure using various models for chemical bonding; the structure and properties of aromatic and heteroaromatic molecules; the phenomena of electron delocalisation (resonance); to explain aspects of conformation, isomerism and chirality within molecules; to provide an introduction to the thermodynamics of solutions; and to cover key concepts in chemical reaction kinetics and redox processes.
On successful completion of the course students should be able to demonstrate a working knowledge of the basic principles of physical, inorganic and organic chemistry sufficient to recognise their involvement in biological and other areas.
More specifically, students should be able to:
• State or calculate values associated with a given atom or ion (e.g. atomic / mass number, number of protons / neutrons / electrons, relative atomic mass)
• Determine the electronic configuration and draw orbital energy diagrams using Hund’s rule and the Pauli exclusion principle
• Draw and interpret Lewis structures (including formal charges) for molecules containing H, C, N and O, and predict their geometry based on VSEPR theory
• Identify characteristics of a given atom or molecule (e.g. hybridisation state, relative bond length, bond polarity, molecular dipoles, hindered bond rotation)
• Identify characteristics of biologically-important molecules (e.g. conjugation, planarity, resonance forms, aromaticity, number of pi-electrons)
• Identify chiral molecules and chiral centres of molecules with biological relevance
• Assign groups of molecules as being identical, distinct or isomeric (including constitutional, geometric and optical isomers)
• Identify simple functional groups and interconvert structures and standard names of simple, biologically-relevant molecules.
• State and calculate equilibrium constants and describe the behaviour of reversible reactions using Le Chatelier’s principle
• Calculate the pH of solutions of both strong and weak acids, and of solutions containing buffers
• Calculate the Gibbs free energy from enthalpy and entropy, and from an equilibrium constant and relate this information to the equilibrium position of a reversible reaction
• Calculate the enthalpy of combustion using Hess’s law
• Use transition state theory to relate the free energy barrier and rate of a reaction
• Determine the rate equation for a given reaction and use the concentration-dependence of an observed rate constant to determine the rate order
• Characterise biologically-important reactions as oxidation or reduction reactions and determine reduction potentials from their Nernst half-reactions
CHEM10111 is taught as six topics, or learning modules (LMs):
LM 1. Atoms, ions and molecules; the periodic table and periodicity; atomic structure; electron configurations.
LM 2. Chemical bonding and non-covalent interactions.
LM 3. Functional group recognition and reaction types.
LM 4. Stereochemistry and chirality; resonance and aromatics;
LM 5. Equilibria, pH and buffers; basic thermodynamics.
LM 6. Oxidation and reduction; reaction rates.
Transferable skills and personal qualities
Problem solving and reasoning.
Numerical skills (mathematical calculations).
- Analytical skills
- Analytical skills may be developed through problem-solving clinics and e-learning modules
- Oral communication
- Students are encouraged to ask and answer questions during lectures and workshops.
- Problem solving
- Students have the opportunity to develop their problem solving skills in problem-solving clinics workshops and eLearning modules
Feedback is via two in person workshop/problem solving clinics/revision sessions each week.
There are also regular online quizzes (ePBL tests) that provide feedback via formative (practice) tests.
There are also drop-in sessions for CHEM10111 run by PASS Leaders throughout the semester. The leaders are higher year students in the School of Biological Sciences who took CHEM units in their first year.
