Assignment title Functional group chemistry for designer molecules Assessor Issue date Hand in deadline Vocational Scenario or Context You are a junior technician working for Reckitt Benckiser at their research and development base in Hull (UK). The products made by this company include Vanish and Mr Sheen. Each year the research laboratories invite a small group of ‘A’ level and ‘BTEC’ students in for two weeks of work experience. This year you have been given the responsibility of preparing an instructional video or presentation and accompanying handbook that will be used on the first day of the student’s work experience. The purpose is to ensure the work experience students have the basic knowledge they will need about the structure, reactions and properties of carbonyl and non-carbonyl organic compounds. Task Using your lesson notes and research you have carried out into the structure, reactions and properties of functional group compounds, produce a handbook on functional group chemistry. Begin your handbook by defining functional groups and their relevance to reactivity of organic compounds. Write sections of your handbook by functional group, explaining how and why they react the way that they do, for the following: · Halogenoalkanes and their reactions (nucleophilic substitution and elimination) · Alcohols (primary, secondary and tertiary) and their reactions (oxidation) · Amines (primary, secondary and tertiary) and their reactions (as bases and nucleophiles) · Aldehydes and ketones and their reactions (oxidation & reduction; nucleophilic addition and addition-elimination) · Carboxylic acids and their reactions (as acids; addition-elimination to form esters) · Acyl chlorides, acid anhydrides and amides, and their reactions Each section will be illustrated with balanced equations and reaction conditions, and include nomenclature and structural formulae of all starting materials and products, including commercially important products, formed. The handbook must next have a section on mechanisms, in which you which will construct and analyse an example of each of the following reaction mechanism types: · Addition e.g. aldehyde or ketone with HCN · Substitution e.g. halogenoalkane with aqueous NaOH · Elimination e.g. halogenoalkane with ethanolic NaOH · Addition-elimination e.g. aldehyde or ketone with 2,4-dinitrophenylhydrazine This section must explore and interpret the similarities and differences between each of the four mechanisms. For the final section, use relevant information from the other sections of your handbook, to give a plan of a multi-step synthesis of · ethyl ethanoate (CH3CO2CH2CH3), starting from ethanol and ethanal · N-ethylacetamide (CH3CONHCH2CH3), starting from chloroethane and ethanoyl chloride You will need to include reagents, reaction conditions and intermediate products involved in each step. Your handbook will be much more interesting to your audience if pictures of 3D models of your molecules are included where it is appropriate. Finally, prepare an instructional video or presentation, using your pictures and diagrams to accompany your verbal presentation and explanation of your handbook content. Checklist of evidence required An instructional video recording or presentation which: · Uses pictures and diagrams to illustrate your verbal explanation of the content of your handbook. A hand book to accompany the video or presentation which: · Explains the typical non-carbonyl and carbonyl reactions included in the task, to include correct names and formulae of starting materials and products, balanced equations, reaction conditions and any commercially important products; · Shows plans of the multi-step synthesis routes for a) ethyl ethanoate (CH3CO2CH2CH3), starting from ethanol and ethanal and b) N-ethylacetamide (CH3CONHCH2CH3), starting from chloroethane and ethanoyl chloride; · Gives an analysis of the typical reaction mechanisms (substitution, addition, elimination and addition-elimination) that you have constructed, interpreting the similarities and differences between each of the mechanisms. Sources of information must be appropriately referenced. Correct scientific terminology must be used. Criteria covered by this task: Unit/Criteria reference To achieve the criteria, you must show that you are able to: A. D1 Analyse the types of reaction mechanisms undergone by non-carbonyl and carbonyl compounds. A.M1 Construct mechanisms for non-carbonyl and carbonyl compounds. A. M2 Plan a multi-step synthesis of carbonyl and non-carbonyl organic molecules in order to produce many organic substances, taking more than one reaction step. A. P1 Explain the reactions of a range of carbonyl and non-carbonyl functional group compounds.
