Hydrocarbon Collab Activity

Hydrocarbon Finale

Before we start looking at the fun stuff - alcohols and carboxylic acids ;)

Today

We are going to have a look at combing all of the topics we have done so far

- The different ways of writing the formula of organic compounds (Full, semi-structural and skeletal)

- How to categorise homologous series

- What Isomers are

Open Ended

But first.. What is a homologous series?

Open Ended

What do we mean when we talk about isomers? What are they?

Multiple Choice

Is this an alkane, alkene or alkyne?

• Alkane

• Alkene

• Alkyne

Multiple Choice

Is this an Alkane, Alkene or Alkyne

• Alkene

• Alkane

• Alkyne

Multiple Choice

What is the correct description of FULL Chemical Formula

• Show all atoms and bonds

• Show all atoms and bonds but you can leave out the hydrogen

• Show all atoms but not the bonds, just the order of bonding

• Show only carbon to carbon bonds as lines, nothing else

Multiple Choice

What is the correct description of semistructural formula?

• All atoms and bonds

• All atoms and bonds with no hydrogens shown

• No bonds shown, only atoms and the order of how they are bonded

• Just carbon to carbon bonds shown as lines, no atoms shown

Multiple Choice

What is the best description of skeletal formula?

• All atoms and bonds shown

• All bonds but with no hydrogens shown

• No bonds shown, only atoms and the order of bonding is idnicated

• Only carbon to carbon bonds shown with nothing else

Each person on you table will get two molecules

• •Name the molecule

  •What Homologous Series it belongs too

  •Write the semi structural formula

  •Write the skeletal structure

  •Write the chemical formula

Swap your molecule with the person next to you

• •Name the molecule

  •What Homologous Series it belongs too

  •Write the semi structural formula

  •Write the skeletal structure

  •Write the chemical formula

Now share your answer with the person you swapped with

• •Did you come up with the same answers? 

  •If you did not, try to come up with a consensus between the two of you

  •If you STILL cannot come to a consensus, then ask me!

Now it is time to categorise your molecules!

Categorise your molecules into different homologous series

Categorise your molecules into isomer groups
