Skeletal structure of organic compounds

Question

What are the skeletal structure of following compounds
A) CH3CH2C(CH2)2CH3
B) C(CH3)3(CH2)3CH3

Answer 1

Hello Alexa

 

As J.R.S mentioned, it is rather difficult to draw the skeletal "line" structures of your 2 compounds here as there is no Chem draw feature available.

 

A) CH₃CH₂C(CH₂)₂CH₃

 

For Structure A, there is an error in the way it is written specifically in the 3rd carbon from the LEFT side.  Carbons must always have 4 bonds, but this C-3 carbon as only 2 bonds as illustrated by the condensed structural formula below:

 

CH₃−CH₂−C−CH₂−CH₂−CH₃

                 ↑

           **error**

 

Can you kindly re-check your original question and then post the correct structure here?  Thank you!

 

 

Structure B

 

B) C(CH₃)₃(CH₂)₃CH₃

 

The condensed structural formula is (hopefully the formatting does not get distorted):

 

        CH₃

         l

H₃C−C−CH₂−CH₂−CH₂−CH₃

         l

        CH₃

 

I will attempt to draw the line skeletal structure below, but again, the structure will look weird due to the lack of a drawing feature in this forum.  FYI - The name of this compound is 2,2-dimethylhexane.

Answer 2

Skeletal structures are basically the carbon (C) chains and side groups without the hydrogens attached.  They are difficult to draw on this web site. Butane would like something like this   ⁄\/\

That's a pretty poor representation, but hopefully you'll get the idea.  Maybe someone else has a better way of showing the skeletal structure on this web site.  I'd be interested.
