Chemistry

A LEVEL CHEMISTRY

Suitable for Exam Boards:
AQA (7405) & OCR A (H432)
Course Code:
A1CHEAQR

+ Course Dates April 2019

  • 08-11 (Monday – Thursday) – Course Full
  • 11-14 (Thursday – Sunday) – Course Full

A Level courses include 21 hrs of tuition taken over 3.5 days. It is ESSENTIAL that you read the accompanying course outline(s) before applying for the course.

+ Aim

The aim of this course is to revise the topics included in these two A-Level Chemistry specifications. As far as possible, the sessions will be tailored to the needs of the students. Tutors will make every effort to overcome individual difficulties, whilst still providing an overview of both syllabuses. Although the courses by these two exam boards might be structured differently, virtually all of the material is identical. Nonetheless, tutors will endeavour to alert students to content that is unique to one board and highlight any differences in the style in which questions are asked. Both Year 1 and Year 2 material will be covered over the 3.5-day course.

The emphasis of this course will be on examination technique, as well as the consolidation of basic concepts and facts. Past paper questions will be completed through, and mark schemes and examiners’ comments provided.

+ Key Topics Covered

Acid-base reactions.

Redox: oxidation, reduction and half-equations.

Energetics: enthalpy changes, calorimetry, application of Hess’s law, bond enthalpies.

Kinetics: collision theory, the Maxwell-Boltzmann distribution, explaining the effects of temperature, pressure and catalysis.

Qualitative analysis: test-tube reactions to identify aqueous ions.

Period 3: trends in the physical properties of Period 3 elements (atomic radius, first ionisation energy, melting point), trends and reactions of their oxides.

Transition metals: complex formation, substitution reactions, shapes of complex ions, formation of coloured ions, variable oxidation states.

Organic Chemistry

Basic concepts: nomenclature, formulae, reaction mechanisms, isomerism.

Alkanes: production, structure, properties, reactions.

Halogenoalkanes: synthesis, substitution and elimination reactions, CFCs and ozone depletion.

Alkenes: structure, addition reactions, addition polymers.

Alcohols: structure, properties, production routes, oxidation, elimination reactions.

Analysis: identification of functional groups by test-tube reactions, atomic/molecular mass spectrometry, infra-red spectroscopy.

Aromatic chemistry: Kekulé and delocalised bonding models of benzene, thermochemical evidence for the delocalisation stability, electrophilic substitution reactions (nitration, Friedel-Crafts), phenol, directing group effects.

Carbonyl compounds: aldehydes, ketones, carboxylic acids and their derivatives (esters, acyl chlorides, acid anhydrides).

Amines: preparation, basicity, reactivity as nucleophiles, amino acids.

Biochemistry: proteins, DNA, enzymes, anti-cancer drugs (AQA only).

Polymers: monomer pairings, drawing structures and repeating units of condensation polymers, biodegradability.

Organic synthesis: identification of functional groups, atom economy, devising multi-step syntheses (up to four steps).

Chromatography: TLC, CC, GC, GC-MS, Rf values and retention times.

NMR: interpreting 13C and 1H NMR spectra, identifying unique environments, use of TMS as a standard.

+ Assessment

The course will include homework to be completed each night and students will answer mock exam questions to enable feedback.

+ Course Materials

Students should bring copies of their own specifications and their main textbooks. A scientific calculator will also be required. All other materials will be provided.

+ Other Information

The course is not suitable for students taking the OCR Chemistry B (Salters) course (H433).

Note that this course will cover only theory and exam technique; no practical work will be undertaken.

Please note that the emphasis given to particular topics will be weighted to the needs and requirements of the candidates in the group.
