Unit 28: Organic Chemistry Reactions

This assignment, part of a BTEC Extended Diploma in Applied Science, focuses on the reactions of functional groups and multistep synthesis in organic chemistry. Students are tasked with creating a leaflet describing reactions of non-carbonyl functional groups (haloalkanes, alcohols, and amines), completing a worksheet predicting products of reactions involving carbonyl compounds, and developing synthesis maps for multi-step reactions to produce target molecules from given starting molecules. The assignment assesses their understanding of organic reaction mechanisms and their ability to plan and execute multi-step syntheses. Resources such as textbooks and online chemistry resources are provided.

Assignment title 28.2 Reactions of Functional Groups and Multistep Synthesis
Purpose of this assignment
Allow learners to begin to build up the bigger picture of organic chemistry by studying the reactions of
simple functional groups and how organic compounds link together by looking at ways in which
compounds can be synthesised from others.
Scenario
The petrochemical plant you work for have asked you to produce some information to help
employees understand more about the chemistry behind their roles. This must include the
reactions of the variety of different functional groups and the ways in which organic
molecules can be synthesised from others.
Task 1 – Reactions of Non-Carbonyl Functional Groups
We have looked in detail at the properties and reactions of haloalkanes, alcohols and
amines.
Produce a leaflet that provides an overview of the reactions of haloalkanes, alcohols and
amines. Your leaflet must include the following :-
 The conversion of haloalkanes into alcohols
 The reaction between haloalkanes and ammonia
 The reaction between haolalkanes and amines
 The reaction between haloalkanes and hydroxide ions under reflux
 The formation of PVC
 The oxidation of primary, secondary and tertiary alcohols
 The reaction between ethanol and sodium
 the elimination of water from alcohols
 The reaction of amines with acid.
This provides evidence for P3
Task 2 – Reactions of Carbonyl Functional Groups
Complete worksheet 1 on the reactions of carbonyl functional groups.
You will use your knowledge of organic reactions to predict the products for reactions
involving the following carbonyl compounds:
Aldehydes, Ketones, Carboxylic Acids, Esters, Acyl Chlorides and Amides.

This provides evidence for P4
Task 3 – Multistep synthesis of organic molecules
Produce a synthesis map or a list of reactions to show how you would carry out multi-step
reactions to produce the desired product from a given starting molecule.
Starting molecule: alcohol Target Molecule: carboxylic acid
Starting molecule: ethene Target Molecule: haloalkane
This provides evidence for M3
Task 4 – Synthesis Map of Organic Compounds
Use your synthesis map from task 3 and include more multi-step reactions showing the
syntheses of a wide range of organic compounds.
For example you could include the synthesis of aldehydes, ketones, carboxylic acids,
haloalkanes, alcohols.
This provides evidence for D3

Reactions of Carbonyl Compounds(P4)
Below is a general outline of the different types of reactions that carbonyl compounds can
undergo showing starting materials and conditions.
Write an equation for each reaction and the products produced.
Written by Amjad Iqbal 18-7-16 IV’d Fran Hooley 20-7-16

Aldehydes and ketones can both be reduced respectively using a suitable reducing agent
such as NaBH4 under gentle heating.
Aldehydes can be oxidised using acidified potassium dichromate under reflux.
Carboxylic Acids can be reacted with alcohols using an acid catalyst
Esters reacted with water using hydrochloric acid.
Acyl Chlorides reacted with water under standard conditions .
Amides can be reduced by reaction with lithium tetrahydridoaluminate, LiAlH4, in dry ether
(ethoxyethane) at room temperature.
