Overview

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.

 

 

Aims

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.

 

Learning outcomes

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
 

 

Syllabus

  • 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.

Assessment methods

Method Weight
Written exam 80%
Set exercise 20%

Feedback methods

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.
