S2 Chemistry - Hydrocarbons and Plant Products

This set of vocabulary flashcards covers introductory organic chemistry (alkanes, cycloalkanes, alkenes), industrial processes like cracking, and the uses of plant products as outlined in the S2 Chemistry curriculum at St Ninian's High School.

First 8 Alkanes

The names and molecular formulas are: Methane ($CH_4$), Ethane ($C_2H_6$), Propane ($C_3H_8$), Butane ($C_4H_{10}$), Pentane ($C_5H_{12}$), Hexane ($C_6H_{14}$), Heptane ($C_7H_{16}$), and Octane ($C_8H_{18}$).

First 6 Cycloalkanes

The names and molecular formulas are: Cyclopropane ($C_3H_6$), Cyclobutane ($C_4H_8$), Cyclopentane ($C_5H_{10}$), Cyclohexane ($C_6H_{12}$), Cycloheptane ($C_1H_{14}$), and Cyclooctane ($C_8H_{16}$).

First 7 Alkenes

The names and molecular formulas are: Ethene ($C_2H_4$), Propene ($C_3H_6$), Butene ($C_4H_8$), Pentene ($C_5H_{10}$), Hexene ($C_6H_{12}$), Heptene ($C_7H_{14}$), and Octene ($C_8H_{16}$).

Bromine Solution Test (Alkenes)

A chemical test where bromine solution reacts with alkenes and rapidly decolourises.

Bromine Solution Test (Alkanes and Cycloalkanes)

Alkanes and cycloalkanes do not decolourise bromine solution.

Cracking

The process of breaking down larger hydrocarbons into smaller, more useful products.

Cracking Products

Chemical reactions that produce a mixture of alkanes and alkenes.

Plant Products in Society

Materials derived from plants that benefit society, such as medicines, dyes, and fuels.

Fermentation

The process that makes alcohol from glucose in plants.

Biomass Energy Resources

Renewable energy sources made from natural materials that have various advantages and disadvantages for society.
