Chapter 6 Organic Chemistry Flashcards
Name one saturated hydrocarbon
Ethane
Name the polymer of ethene
Polyethene
What are hydrocarbon
Compounds containing hydrogen and carbon
Name one unsaturated hydrocarbon
Ethane
What’s an Alkanes
They are saturated hydrocarbon containing only single covalent bonds between carbon atoms
Why is it that ethene can take part in addition reaction than Ethan
Because of double bond of alkenes allow it in addition reaction
What’s the product formed when bromine and ethene combine
Form dibromoethene
What’s bromination
Bromine reacts with ethene produce dibromoethene
Name some additional reaction
Hydrogenation
Hydration
Chlorination
What are monomers
Smaller molecules
Name one hydrocarbon can be coveted to a polymer
Ethene
What term is used to describe a reaction of glucose changed to ethanol
Fermentation
What’s fermentation
It’s a process used in production of ethanol from sugar by the action of yeast or bacteria on it
What’s the purpose of yeast in the fermentation process
Act as a catalyst
Which homologous series does ethanol belong to
Alkanols or alcohols
Why does ethanol become sour when exposed to the air
Oxidation occurs which leads formation of an acid or carboxylic acid which has a sour taste
What product is produced when ethanol is dehydrated
It produces ethene
What’s dehydration
The removal of water from a compound
Ethene plus steam gives
Ethanol
What process used to separate the fraction of crude oil
Fraction distillation
What major elements are found in crude oil
Hydrogen
Carbon
What does non renewable energy source mean
Source is one that is limited supply and can not be replaced once used
Why is the sun better source of energy than crude oil
It is inexhaustible
Solar energy can be clean process while crude oil causes pollution
What reaction occurs in petroleum industry
Catalytic cracking
What are suitable condition for catalytic cracking to occur
Presence of a catalyst
High temperature around 500 *c
What’s cracking
The process of were large hydrocarbon are broken in molecules break into smaller molecules
What’s an isomer
It is a compound with the same molecular formula but different molecular structure
What macromolecule is formed when butene is polymerized
Polybutene
What is the reaction when ethanol produces ethanoic acid
Esterification
What’s the reaction when ethanol produces ethylethanoate
Is oxidation
What reagent brings a change when produce ethylethanoate
Ethanoic acid
What are used of esters
Making perfume
What product given out in cracking
An Alkanes with a shorter chain than before
A short chain of alkene molecule
What are esters
They are organic compounds formed by acids and alcohol
Name some examples of esters
Vegetable oil
Animal fats
What type of reaction is nylon formed from diaminohexane or hexanedioyl chloride
Condensation polymerization
Apart from nylon name another compound formed by diaminohexane and hexanedioyl chloride
Hydrogen chloride
Name a macromolecule and type of linkage which is similar to that of nylon
Protein
Amino linkage
What’s the use of nylon
As a synthetic fibre In clothing Carpet Rubber reinforcement Computer ribbons Sewing thread
What’s polymerization
This is a chemical reaction which a macromolecule known as a polymer is formed by the condensation of many identical monomers
What does the team unsaturated hydrocarbon mean
It’s a carbon containing at least one double bond among its carbon atoms
What’s the Colour of dibromoethene
It’s a colourless compound
