Organic Chemistry Modelling 2

I have started to build some common functional groups and related molecules. Here we have the Basic HydroCarbon Benzine ( C6 H6, by adding the OH (Alcohol) functional group we get Phenol (2nd picture). ( C6 H5 OH ).

Benzine

Phenol

We looked at basic Alkanes yesterday, if we take,for example Methane ( CH4 ) we can replace a Hydrogen with a OH group (Oxygen + Hydrogen) to make methanol. ( CH3 OH)

Organic Chemistry Modelling

I have been building some organic Chemistry models with Molymods, starting with the first 10 alkanes.

Methane Ethane Propane Butane Pentane hexane heptane octane nonane decane

The order of these are

  1. Methane
  2. Ethane
  3. Propane
  4. Butane
  5. Pentane
  6. Hexane
  7. Heptane
  8. Octane
  9. Nonane
  10. Decane

So going from top to bottom, you get an indication of the number of Carbon atoms in the chain. So 1 for Methane and 10 for Decane.

The general rule is CnH2n+2 BBC Bitesize.

Organic Chemistry 1 (Basic Alkanes)

So following on from molecular-modelling-with-clay-part-1

I am going to stick to using the actual molymod kits. However, feel free to use clay if you don't have access.

So I have built

  • Methane ${CH4}$
  • Ethane ${C2}{H6}$
  • Butane ${C3H8}$
  • Propane ${C4H10}$
  • Pentane ${C5H12}$

I have presented how these look in the video below.

So this shows you what these molecules look like using spacefill.

And below is a basic construction guide.

The following infographic may be useful here.

You may find Molview helpful for visualising molecules on your computer screen too. This could complement physical building which I find can help understanding further.

Further help and questions

If you would like any further help with chemistry (or any other science subject) then I have found ScienceForums to be a very useful, friendly and educational forum.

Free signup and there is a section there on homework help. As long as you follow the forum guidelines then someone should be able to help, don't forget to upvote any answers.

Feel free to tag me in to posts @paulsutton, I am sure there are others who may be more able to help with specific questions on science generally.
