#13 Sapling Week 8

Postby Ruth Rosales 3D » Sun Nov 29, 2020 5:36 pm

Having trouble with this question:

"A 3D representation of a cyclohexane ( C6H12 ) molecule, a cyclic compound used in the manufacture of nylon and found in the distillation of petroleum, is shown.

Name the geometry around each carbon atom."

I thought it might be tetrahedral or trigonal pyramidal but is marking it wrong. Would any one be able to clarify this?

tetrahedral is correct! if it's not cooperating when you write that in maybe its a spelling error? otherwise i'm not sure how to help :(

Four regions of electron density indicate a tetrahedral geometry, so that response would be correct. I am not sure why it marked yours wrong (my response was marked as correct). I hope this helped!

I think I put tetrahedral for that so I am not sure what may have gone wrong. Maybe check your spelling?

Hi there! Tetrahedral should be the correct answer for this question. Perhaps check spelling or if they're picky about capitalizations? It should be marked correct. Hope this is helpful!

since each carbon atom has 4 regions of electron density (4 bonds) the shape is tetrahedral

Tetrahedral is the correct answer because each carbon atom, the bonded atom point towards the corners of a tetrahedron.

I had the exact same problem! This was also one of the last problems that I had to answer and it was really stressing me out. But no worries, I'm sure many of us were confused by this one.

Since each carbon atom has four bonded regions, that would make it tetrahedral!

It is a tetrahedral so I imagine it is just a spelling error.

Tetrahedral would be correct, make sure you answered the question below it. I think the answer should be sp3. If that doesn't work then your Sapling must be glitched

when you take a look at each individual carbon atom, it contains 4 bonding regions, making the shape tetrahedral.

The shape would be tetrahedral because the carbon has four regions of electron density. These four regions are the two bonds with hydrogen and the two bonds with the neighboring carbons.

This should be tetrahedral because it would have the correct amount of bound molecules.

tetrahedral is correct because each carbon atom has 4 other connecting atoms and no lone pairs. This is tetrahedral, check if you completed the whole question like part b

It should be tetrahedral because there are four bond atoms to the central atom.

The shape is tetrahedral as the carbon has 4 areas of electronegativity with no lone pairs. And maybe sapling is marking you wrong because of a spelling error but I hope you were able to fix it !

It is tetrahedral! Check your spelling and if that doesn’t work maybe try refreshing the page, because if it’s saying that it is incorrect that is an error :)
