Chemistry Advanced Higher

RECOMMENDED ENTRY:

While entry is at the discretion of the Principal Teacher, candidates will normally be expected to have attained a Higher Chemistry award or its equivalent:

The Course builds on Higher Chemistry, developing further the underlying theories of chemistry and the practical skills used in the chemical laboratory.

The study of chemistry at Advanced Higher level develops the candidate’s knowledge and understanding of the physical and natural environments. The Course also develops the skills of independent study and thought that are essential in a wide range of occupations.

The Advanced Higher Chemistry course is divided into three units of study and a practical investigation.

1. Electronic Structure and the Periodic Table (20 hours)

Performance criteria

(a) Knowledge and understanding of electronic structure is clearly shown in appropriate ways.

(b) Knowledge and understanding of chemical bonding is clearly shown in appropriate ways.

2. Principles of Chemical Reactions (40 hours)

Performance criteria

(a) Knowledge and understanding of stoichiometry is clearly shown in appropriate ways.

(b) Knowledge and understanding of chemical equilibrium is clearly shown in appropriate ways.

(d) Knowledge and understanding of reaction feasibility is clearly shown in appropriate ways.

(e) Knowledge and understanding of electrochemistry is clearly shown in appropriate ways.

(f) Knowledge and understanding of kinetics is clearly shown in appropriate ways.

3. Organic Chemistry (40 hours)

Performance criteria

(a) Knowledge and understanding of some permeating aspects of organic chemistry is clearly shown in appropriate ways.

(b) Knowledge and understanding of systematic organic chemistry is clearly shown in appropriate ways.

(d) Knowledge and understanding of structural analysis is clearly shown in appropriate ways.

(e) Knowledge and understanding of medicines is clearly shown in appropriate ways.

4. Chemical Investigation (20 hours)

Candidates should provide a completed record with:

• notes/comments on ideas rejected

• notes/comments on planning and design

• contributions made by other individuals

• notes/comments on selection of method used

• notes on risk assessment.

• is the individual work of the candidate

• has been obtained with due accuracy.

Experimental information should be analysed and presented using the following as

appropriate:

• sources of error

• estimate of error

• calculations

• factors affecting yield

• reference data, e.g. for identification of products

• tabular presentation of derived and final results

• graphical presentation of derived and final results.

In addition all candidates will be expected to carry out the Prescribed Practical Activities listed below.

Prescribed Practical Activities
Preparation of Potassium Trioxalatoferrate(III)	Unit 1
Colorimetric Determination of Manganese in Steel	Unit 1
Complexometric Determination of Nickel using EDTA	Unit 2
Gravimetric Determination of Water in Hydrated Barium Chloride	Unit 2
Determination of a Partition Coefficient	Unit 2
Verification of a Thermodynamic Prediction	Unit 2
Kinetics of the Acid-Catalysed Propanone/Iodine Reaction	Unit 2
Preparation of Cyclohexene	Unit 3
Identification by Derivative Formation	Unit 3
Preparation of Benzoic Acid by Hydrolysis of Ethyl Benzoate	Unit 3
Preparation of Aspirin	Unit 3
Aspirin Determination	Unit 3

Examination Arrangements

External assessment will consist of the following two components:

To gain the award of the Course, candidates must pass the internal assessments for the Units. In addition the candidate must meet the standards targeted by the external assessments.

Written examination (2 hours 30 minutes) 100 marks

Investigation Report 25 marks.

The paper will be divided into the following sections:

Section A Fixed-response questions 40 marks

Section B Extended-answer questions 60 marks.

Section A will be made up of 40 multiple-choice questions.

In Section B approximately 6 marks will be allocated to questions which draw on the candidates’

experience of the prescribed practical activities.

Of the 100 marks in the written paper, between 50 and 55 marks will be allocated to the assessment

of knowledge and understanding and between 45 and 50 marks will be allocated to the assessment of problem solving.

Up to 10 marks over the paper can be allocated to questions based on the content of Higher

Chemistry, with assessment at a level appropriate to Advanced Higher.

Candidates will be expected to answer all questions.
