Description

This unit introduces and explores key fundamental themes used throughout chemistry. It aims to do so in a qualitative way to focus on the broad ideas and implications. Key ideas include orbitals, energy, quantisation and bonding, why reactions happen, shapes of molecules, mechanisms, rates of reaction and measurements. It will also develop themes in the areas of main group chemistry, spectroscopy and thermodynamics. Key topics include periodicity, solid-state chemistry, quantum mechanics, vibrational and rotational spectroscopy, forces and supramolecular interactions.

This unit aims to introduce students to fundamental ideas in chemistry and practical chemistry which will be developed throughout their studies. The implications of these fundamental ideas are illustrated with real world examples to set them in context and highlight their relevance in the modern scientific world.

Units aims:

To provide students with a broad and balanced appreciation of key chemical concepts

To provide students with an appreciation of key concepts in physical and inorganic chemistry

To develop in students fundamental practical skills

Intended learning outcomes

  • Explain energy quantization, energy levels, and their connection to spectra
  • Discuss quantum numbers of electrons in an atom
  • Predict the shape of covalently bonded molecules, and name (systematic and trivial) functional groups and organic molecules
  • Predict the geometry, name and draw the isomers of organic and inorganic complexes
  • Define the terms electrophile, nucleophile, acid and base and an explain their roles within a reaction
  • Use curly arrow representation to indicate electron flow and therefore mechanism
  • Discuss the relationship between structures and spectra
  • Recognise the limitations/extent of information obtained from each spectroscopic method (both qualitative and/or quantitative)
  • Recognise periodicity and its implications to structure and bonding
  • Describe lattices and the structure of solids
  • Discuss the Schrodinger equation, wavefunctions and quantization
  • Explain spectroscopy as transition between states: Rotational and vibrational states
  • Explain non-bonded interactions and compare them to conventional bonding
  • Importance of non-bonded interactions in gases, liquids and large molecules
  • Discuss entropy and its relation to spontaneous change
  • Explain the formation of chemical equilibria and phase behaviour
  • Recognise the interrelationship between all branches of chemistry and between theory and applications

Intended learning outcomes for practical chemistry

At the end of this course, students should be able to:

  1. Identify procedural and chemical hazards and operate effectively, safely and efficiently to carry out an experiment within the allotted time.
  2. Know when and how to: o Maintain an up-to-date lab book with accurate calculations and experimental observations o Interpret and follow experimental instructions o Correctly weigh out chemicals o Prepare solutions of accurately known concentration o Assemble and correctly use simple laboratory apparatus o Reflux solutions o Separate liquids and extract suspensions o Recrystallise impure solids o Filter solids using gravity or vacuum (Hirsch and BĪ‹chner) methods o Evaporate liquids o Titrate solutions o Select appropriate glassware for use
  3. Interpret and manipulate data sets using Excel and present results using Word
  4. Analyse and interpret results and spectra from a range of analytical techniques including NMR, IR, UV-Vis, Melting point and TLC

Teaching details

Lectures, small group tutorials, workshops (classes of 20 students with two staff members), laboratory classes and independent study. A small amount of pre-tutorial online material will be provided to assist students with tutorial work. Self test multiple choice questions.

Assessment Details

1-hour exam (Multiple choice questions, computer based, 100% formative delivered in TB1)

One 2-hour written exam in TB2 (100% summative)

Continuous assessment of the laboratory skills detailed in the Intended Learning Outcomes. Practicals in the first 18 weeks will be formatively assessed, giving the students the chance to learn and practice the skills, which will then be summatively assessed in week 19-24. Students will be allowed to discard the marks from two of the assessments, leading to the unit mark being composed of the best 4 of their 6 marks.
