A homologous series of organic compounds have the same general formula, and show similar chemical properties and physical property trends.

The functional group is the atom or group of atoms responsible for the way a compound reacts.

Calorimetry is an experiment that can be used to measure the energy released from a fuel.

Viscosity is how easily a liquid flows. The higher the viscosity, the less easily a liquid flows.

Chemical tests involving alkanes, alkenes and alcohols

Chemistry

In the Chemistry of Carbon unit, pupils learned about the structure and bonding of carbon, and its ability to form various compounds.

This unit covers identifying functional groups, naming and drawing structural formulae, and predicting reactions of alkanes, alkenes, alcohols, and carboxylic acids. It explains addition and condensation polymerisation and discusses natural polymers like DNA, sugars, and amino acids.

Organic chemistry

Add sodium carbonate and test for carbon dioxide.

Add hydrochloric acid and observe bubbling.

Add bromine water and observe a colour change.

Which of the following is a test for unsaturation?

As chain length increases, more energy is released during combustion.

As chain length increases, the same energy is released during combustion.

As chain length increases, less energy is released during combustion.

Which of the following statements about chain length is correct?

Sort the following alkenes into order of decreasing viscosity, starting with the most viscous.

Which of the following colour changes, if any, will be observed when bromine water is added to an alkene?

Which of the following colour changes, if any, will be observed when bromine water is added to the molecule shown in the image?

Which of the following molecules will decolourise bromine water?

Sort the following alcohols into order of increasing chain length, starting with the shortest.

What name is given to the atom or group of atoms responsible for the way a compound reacts?
