Naming and Drawing Simple Organic Molecules Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what's on both sides.
  • Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

In names like methane, ethane, propane and butane, what does the part meth-, eth-, prop- and but- tell you?

It tells you how many carbon atoms are in the longest chain: meth = 1, eth = 2, prop = 3, but = 4.

What type of organic molecule has a name that ends in -ane?

An alkane, which has only single bonds between its carbon atoms.

What type of organic molecule has a name that ends in -ene?

An alkene, which has at least one carbon–carbon double bond.

What type of organic molecule has a name that ends in -ol, such as ethanol?

An alcohol.

What type of organic molecule has a name that ends in -oic acid, such as ethanoic acid?

A carboxylic acid.

What is the name of the alkane with four carbon atoms in a row?

Butane.

What is the name of the alkene with two carbon atoms?

Ethene.

What is meant by the molecular formula of a compound?

It shows how many of each type of atom are in one molecule, for example C2H6.

What is meant by the structural formula of a compound?

It shows how the atoms are joined in a molecule, written in a line, for example CH3CH2OH.

What is meant by the displayed formula of a compound?

A drawing that shows all the atoms and all the bonds between them.
