Next Assignment

This is the second assignment. Your performance in this assignment is again going to be used as a judging factor for your eligibility to attend the advanced course.

The assignment is to model any THREE molecules of your choice. You can easily find images on the net which can be used as a reference for designing the molecule. You must maintain its chemical structure, ie if its tetrahedral you must make the same.

We want all the molecules to be unique. So once you have decided on the molecules you are going to model, you must comment on this blog entry and let everyone know the ones you have selected so that two people do not make the same molecule. I repeat, it is very important you first post which molecules you are going to model and then start modelling!

The complexity of the molecule that you choose to model will earn you some extra brownie points, more complex the molecule, better the chances of you being eligible to attend the workshop. But guys do not loose focus and try not modelling molecules that are way to complex and you won't be able to model them correctly hence making the whole process of modelling it redundant as it cannot be used later.

If someone chooses to actually go ahead and make an animation of a chemical reaction using these molecules, nothing like it, but modelling the three molecules accurately must be given top priority.

Some important points- do not make the bonds and the atoms a single object, as later on when we are going to use them to show animated reactions, it might become a stumbling block. Also materials may be used to show atoms of two different elements. At least colour coding must be done to signify two different atoms. If not this then try putting text on them. What method you choose is up to you as long as two atoms can be distinguished.

I am uploading a rendered image of a molecule I had modelled some time back. Notice how the tetrahedron structure has been maintained, ie 60 degrees between the 4 bonds. For guys who arn't quite fluent with chemical terms, the spheres are the atoms and the cylinders are the bonds. The whole thing is a molecule.



Hope this helps. Alright guys thats about it. You have two days time to submit this, i.e. Wednesday midnight. Blend files and rendered images to be mailed to:
catchgokul@gmail.com
You can CC it to Sameer sir also if you like. Best of luck with this, and get modelling!!

C2H6 + O2 CO2 + H2O

its
ethane + oxygen --> carbon-dioxide + water

Sophi said...

I opt to go for H2O[water] & CH4[methane] molecules.
Third molecule??? Do we need to specify [so as to animate] the chemical reaction? I doubt it. Plz clarify.

Nitin Ayer said...

yes specify the 3 molecules and than go ahead with modeling. And as mentioned, if you like than go ahead with animation using same three molecules, but modeling 3 molecules correctly is first priority.

Nitin Ayer said...

Sulphur S8, SF6, PCl5 and benzene

Chirag said...

Here goes : Ethane - Staggered and Eclipsed conformation, Ethylene, benzene

Chirag said...

uh since nitin being over-zealous has taken benzene, I now choose cyclohexane - boat conformation

Priyam said...

@ Sophi.. My point was that take 3 molecules that you later use to animate a chemical reaction, or else you can choose any 3 molecules if you do not want to make the animation. Once people have made there models you can even go ahead to used their molecules to make a reaction. But again modelling must be given first priority in this assignment

Kartik said...

can i some one give me proper structure for nacl ,i am totally lost

Mandar Apte said...

I will do the following Molecule Formula: C8H8O3

i.e. Vanillin Molecule

Vineet said...

I ll go for : Acetic acid, Ethanol and Methyl acetate

Priyam said...

great to see the response guys.. waiting to see the blend files now

Priyam said...

@ chirag - Boss ashay has already taken up ethane please look for something else

Chirag said...

@Kartik: NaCl is an electrovalent bond that is basically Na losing an electron to become Na+ and Cl gaining that to become Cl-..The Cation Anion now fuse to give 1 molecule of Nacl..Im not sure if you can model it like the Organic molecules

Chirag said...

By that logic Ashay's also taken water, so even Sophi needs to find something else

Chirag said...

Yup since ethane's so taken, Ill do 1,2 dibromo ethane

Sophi said...

whos this?????? ;)

Chirag said...

anyone modelling buckminster fullerine c60???

Kartik said...

can any one provide molecular structure for this sodium dichromate-Na2Cr2O7 or Chromium Trioxide (CrO3)

prajakta said...

okay, I couldn't think of any chemical reaction with the molecules i took. It will test my chemistry more than my animation skills.so i guess its

1. ammonia
2. formaldehlyde n
3. 2-Chloro-2-butene

hope thats cool.

Chirag said...

thats actually pretty cool-formaldehyde..didnt think of that one

Mandar Apte said...

Additional data:

I said I am doing Vanilla.

Plus I am also doing following:

Ammonia, Ethanol, H2O

prajakta said...

hey ammonia chor. its already taken!
