Q

Alcohol

A

A homologous series with the hydroxyl functional group (-OH), denoted by the suffix ‘ol’. Have higher boiling points than alkanes, due to the presence of hydrogen bonds. Smaller chains are soluable in water. E.g. butan-1-ol.

Q

Alkene

A

An unsaturated hydrocarbon with the general formula CnH2n. Contain a single carbon double bond, which allows for them to undergo addition reactions. E.g. but-1-ene. Note: methene doesn’t exist!

16
Q

Condensed Structural Formula

A

A formula that shows the structure of the molecule, but not the bonds or the shape. E.g. CH3CH2CH3

17
Q

Crude Oil

A

A fossil fuel formed from the remains of dead animals and plants, which have been buried for millions of years.

18
Q

Dimer

A

Two identical molecules that are bonded together, such as between ethanoic acid.

19
Q

Fractional Distillation

A

The separation of a liquid mixture into fractions (different carbon chain lengths) by heating and cooling.

20
Q

Functional Group

A

An atom or group of atoms that are reactive in a molecule. E.g. hydroxyl group

21
Q

Haloalkane

A

A homologous series with a halogen atom (group 17) replacing one or more hydrogen atoms in an alkane. Denoted by the prefix ‘fluoro’, ‘chloro’, ‘bromo’ or ‘iodo’.

22
Q

Homologous Series

A

A sequence of compounds or molecules with similar chemical properties and the same general formula. Alkanes, alkenes, haloalkanes, alcohols and carboxylic acids.

23
Q

Hydrocarbon

A

A molecule containing only hydrogen and carbon atoms.

24
Q

Hydroxyl Group

A

The functional group in alcohols. -OH

25
Q

Incomplete Combustion

A

When there is an insufficient supply of oxygen during a combustion reaction, resulting in left over carbon in the form of soot.

26
Q

Locant

A

A number used in IUPAC nomenclature which indicates the position of a functional group in a molecule. E.g. but-1-ene.

27
Q

Organic Chemistry

Q

Plant-Sourced Biomass

A

A sustainable renewable alternative to fossil fuels, which sources carbon-material from plants.

31
Q

Structural Isomer

A

A molecule that has the same molecular formula but different structural formula to another. I.e. a different structure of the same molecule. E.g. 3-methylpentane vs 2-methylpentane
