Investigating important organic compounds used in society

Unit 3: Chemistry Applications
Scenario
Science journals publish articles that are topical, are scientifically correct (at the time of being published)
and give any information about both benefits and disadvantages to society. Editors/technical advisers
working for a science journal need to have a good understanding of ethical and moral issues that apply to
science and society.
Organic compounds have had a history of being both essential to society to maintain our standard of living
and having a number of disadvantages in their useage to society and the environment. This has led to a
number of ethical and moral issues and pressures put on different governments to stop disastrous events
happening again.
A science journal wants its technical adviser to prepare and report on the properties of examples of the three
major types of organic compounds, their uses, any environmental consequences and sustainable
development issues of using them in society.

BTEC First Certificate Applied Science
Unit 3: Chemistry Applications
Investigating important organic compounds used in society
Unit 3 learning outcome 3 – Know the importance of organic chemistry.
Unit content covered:
Organic compounds: definition; organic chemicals; carbon cycle
Hydrocarbons: petroleum cracking; alkanes and alkenes (methane, butane,
pentane and octane, and ethene); 2D structures; shapes; applications of
hydrocarbons; polymerisation of ethene and its applications
Halogen-containing organic compounds: chloroethene; polymerisation of
chloroethene (PVC and PVCu) and its applications
Oxygen-containing organic groups: alcohols (ethanol); carboxylic acids
(ethanoic); structures; physical properties and combustion; applications ethanol,
eg alcoholic drinks, biofuels, cosmetics, inks, coatings; applications of ethanoic
acid, eg pickling, manufacture of esters.
Task 1
Research and collect information from suitable sources about the uses of:
 hydrocarbons – to include alkanes and alkenes
 oxygen containing organic compounds to include ethanol and ethanoic acid
 halogen containing organic compounds to include chloroethene.
Explain, with the aid of diagrams, the structure of each type of hydrocarbon and how
this structure gives different properties and therefore different uses.
Task 2
Use the practical investigation worksheets provided to confirm properties of
alkanes, alkenes, alcohols and carboxylic acids. This can include tests such as pH,
solubility in water, tests with bromine water (for alkanes/alkenes), flame test in a
fume cupboard to test for sootiness and addition of ethanol to ethanoic acid to
produce the ester ethyl ethanoate.
Task 3
Use this information to describe the use of the three main types of organic
compounds used in society.
P5
Task 4
Produce a table to list the benefits and disadvantages of using the above organic
compounds in society.
M5
Task 5
Produce and present a poster that evaluates the importance of the above organic
compound used in society.
D5
The grading criteria that this assignment relates to:
P1:
describe atomic and electronic structures of elements 1−20, including isotopes, in the
periodic table
M1:
describe the patterns and trends of chemical properties of groups 1 and 7 in the
periodic table
D1:
explain the patterns and trends within groups 1 and 7 in the periodic table.
