Organic Chemistry: 5 Phenyl Group

As Polystyrene Contains a C6H5 Phenyl group. Before moving on to building this, we can look at similar molecules that also contain this group.

Video should show making of the above compounds with Molymod components.

Tomorrow, I will post a follow up on more benzene based molecules to build. So please keep hold of the C6H6 Benzine model.

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.

Organic Chemistry 4 : Plastics

Previous post

Moving on lets have a look at:-

I have built this using Molymods in the video below, Just imagine that the rest of the white atoms (hydrogen from previous video) are in fact green, Chlorine atoms.

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.

I will post a few more videos showing the other molecules in that section of the infographic.

**Note: ** Polytetrafluoroethylene. It appears that Polytetrafluroethylene and Polytetrafluroethene are the same molecule, with different spellings depending on if you're using US or GB English.

Organic Chemistry 3 Plastics

Following on from organic-chemistry-2 we have had a look at Alcohols. So will now turn some attention to plastics.

So again we can construct models of plastics in a similar way, the main difference here is that plastics are POLYMERS, which are MONOMERS chained together.

Mono – Single Poly – Multiple

So looking at the above you will notice that they are using n to indicate there is more than 1 in the chain.

So starting with ${C2H2}$ or Ethene, this becomes Polyethene when more monomers are added to the chain.

So in the video below, I construct Ethene and then, in the spirit of Blue Peter, I am then using a few more I made earlier.

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.

I will post a few more videos showing the other molecules in that section of the infographic.

Organic-chemistry-2

So following on from organic-chemistry-1. Lets have a quick look at another group: Alcohols.

SO following the same naming convention as Alkanes, we name Alcohols in a similar way.

• Methanol ${CH3OH}$
• Ethanal ${C2}{H5}{OH}$
• Butanol ${C3H7}{OH}$
• Propaol ${C4H9}{OH}$
• Pentanol ${C5H11}{OH}$

So in the video below. I have taken Methane and Pentane and made Methanol and Pentanol respectively from these.

As an extension to this, we can of course also construct 3-Pentanol where the Functional alcohol group is on the 3rd carbon along the chain. See video below.

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.

Hopefully this is helpful. Have fun.

Nethack Vulture scores 5/8/2020

Just sharing my latest scores from Nethack-vulture. I am playing this on FreeBSD.

 No  Points     Name                                                   Hp [max]
1       1078  paul-Arc-Dwa-Mal-Law died in The Dungeons of Doom on
level 7.  Killed by a dog, while helpless.              -  [33]
2        987  paul-Bar-Hum-Fem-Neu died in The Dungeons of Doom on
level 4 [max 5].  Killed by a homunculus, while
helpless.                                               -  [44]


to generate the score type:

nethack -s at the command line. If you direct this in to a file with nethack -s >score.txt, then this will also include scores from previous games.

Overleaf Webinars August / September 2020

Overleaf are presenting their introductory Webinars in August and September.

If you are new to Overleaf then these are really useful to learn about the features from Beginner to Advanced.

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.

Physics news 4th August 2020

Lots of interesting things happening at FermiLab then.

“US CMS is very proud to acknowledge the significant impact made by its members in deploying innovative analysis techniques, including cutting-edge AI methods, which were critical in establishing the evidence for Higgs boson decays into a muon and antimuon pair,”


It may be an idea to have an understanding, or a copy of the standard model of particle physics to hand.

This is also being discussed on the qoto discourse instance. Where there is also an updated standard model graphic.

You may also find Science Forums a good place to discuss.

This has also prompted me to try and figure out how to typeset the basic equation in LaTeX.

\H\longrightarrow \mu^{–} + \overline{\mu^{+}} $So to quote the$\textit{news.fnal.gov}$website • Please ignore the$'s at either side of the equation, these will be removed at some point.

NASA SpaceApps 2020

NASA SpaceApps event is from 2nd to 4th October 2020 and those wishing to participate will need to register with NASA at https://www.spaceappschallenge.org/ from mid August.

In light of the COVID-19 pandemic and in the interest of our global community’s health and safety, NASA and the Space Apps Global Organizing Team have made the difficult decision to make the 2020 hackathon an all-virtual event. Each local virtual event will be hosted by one of our Space Apps Local Leads -- event leaders who will help connect registrants from their local communities to each other and to NASA. All participants will be invited to attend a global opening ceremony on October 2, which will be streamed on YouTube.


The South Devon Tech Jam is looking at perhaps putting a team together for this and will announce details in due course.
