Alkanol + HX

What happens when you add a concentrated hydrohalic acid, like hydrobromic acid or hydrochloric acid or hydroiodic acid, to an alkanol?
A substitution reaction!

Saturation

What does it mean when a Chemist refers to a molecule as saturated or unsaturated?
How do you test a compound to see if it is saturated or unsaturated?
The answers to these questions, with examples, are given in AUS-e-TUTE's new tutorial Saturated and Unsaturated Organic Compounds

AUS-e-TUTE Members should log-in to access the game, test and exam (with worked solutions) on this topic.

Homologous Series

What is a homologous series in organic chemistry?
Homologous series refers to a group of compounds that have:

1. the same functional group
2. constant successive differences in composition

The individual molecules making up a homologous series  are referred to as homologues (or homologs).

Hydrogenation of Alkenes

How can you convert an unsaturated hydrocarbon such as an alkene, into a saturated hydrocarbon (an alkane)?
With the magic of chemistry (a catalyst), you can add hydrogen across the double bond in an alkene!
AUS-e-TUTE has just added new resources to help our members understand this, and to practice answering test questions. Members should log-in to use these new resources.

If you are not an AUS-e-TUTE member, a "free-to-view" tutorial on this topic is currently available at https://www.ausetute.com.au/hydrogenation.html

Equilibrium Constants are Affected by Temperature Changes

Question:
How would the value of the equilibrium constant, k, be affected if the reaction was heated by 1000°c?
(a) if the reaction was endothermic
(b) if the reaction was exothermic

Answer:
(a)  For an endothermic reaction, an increase in temperature will increase the value of the equilibrium constant.
(b) For an exothermic reaction, an increase in temperature will decrease the value of the equilibrium constant.

Classification of Organic Reactions

Organic reactions are reactions in which the reactants and products are carbon-containing compounds, or organic compounds.
The chemical reactions that organic compounds take part in can be classified as:

• substitution reactions
• addition reactions
• elimination reactions
• oxidation reactions
• reduction reactions
• polymerisation reactions
• rearrangement reactions

AUS-e-TUTE has just added new resources including  a tutorial, game and test with worked solutions to help you identify and classify these types of organic reactions. AUS-e-TUTE Members should log-in to use these new resources.

If you are not an AUS-e-TUTE, a free-to-view tutorial is currently available at https://www.ausetute.com.au/organicrxn.html
