Naming Esters the IUPAC Way

IUPAC naming of esters is not a bit hard, it's just a bit different to the way you name other organic molecules.

Follow AUS-e-TUTE's step-by-step guide to :

• naming esters
• drawing the structure of ester molecules
• writing the molecular formula for ester molecules

and you'll be amazed at how easily you can name, and draw the structure of, esters.

Then, when you think you've got the hang of that, why not try our ester naming game?
Or, test your skill with our ester test.
Preparing for an exam? We've got you covered! You can use our ester exam to practice your exam technique before you sit your exam.
And remember, AUS-e-TUTE's test and exam questions come with immediate feedback to help you understand where you go wrong and help you get the next question right.

2015 Chemistry Calendar

Yes, the 2015 Chemistry Calendar is here!
Yes, it's free to download (it's a pdf)!
And yes, it has been redesigned, but you'll have to download one to see why the 2015 Chemistry Calendar is the best calendar we've made so far ........

Naming Alcohols the IUPAC Way

Alcohols are organic molecules that have the OH (hydroxyl or hydroxy) functional group.
Learn how to apply the IUPAC rules for naming different types of alcohols:

• Naming Straight-Chain Alkanols
• Naming Branched-Chain Alkanols
• Naming Straight-Chain Alkanediols

and learn how to classify alcohols as primary, secondary or tertiary at

• Classification of Alcohols

AUS-e-TUTE Members also have access to additional teaching and learning sources.

Writing Chemical Formula

The chemical formula for the ammonium ion is NH₄⁺.
In order to write this formula correctly you MUST show:

• capital (or uppercase) N for the element nitrogen
• capital (or uppercase) H for the element hydrogen
• a subscript number 4 to indicate the presence of 4 hydrogen atoms in the molecule
• a superscript + sign to indicate that the molecule has a positive charge

When you answer a question at ausetute.com.au requiring a chemical formula, you will need to use the buttons on the textbox provided to make a subscript number and a superscript charge sign.

Here is a quick lesson in how to type your chemical formula into the textbox so that it displays the correct formula and not an incorrect formula (like NH4+)

Amides

You spell amine with an "n" and amide with a "d", but what other differences are there?

AUS-e-TUTE has just added new resources for naming primary amides (primary alkanamides).
AUS-e-TUTE Members should log-in to use the new tutorial, game and test.

If you are not an AUS-e-TUTE Members then there is a "free-to-view" tutorial currently available for evaluation purposes at http://www.ausetute.com.au/nampamide.html

Aspartame

In September 2014, NutraSweet Company, producer of the artificial sweetener NutraSweet containing aspartame, announced plans to close its aspartame manufacturing business and focus on more profitable lines of sugar substitutes.

Controversy has surrounded the use of aspartame in food since its introduction in the 1980s.

It has been alleged that aspartame is responsible for causing headaches, Alzheimer's disease, multiple sclerosis, even cancers.

So, what is aspartame and why is it used?
