Organic chem: draw this in line angle structure

[alphaj]

Homework Statement

Draw this formula in line angle structure. CH3CH2OC(O)CH2CC(CH2)3CH(CN)CHO.

Homework Equations

None.

The Attempt at a Solution

I'm confused with the CC(CH2)3 part of the condensed formula. I knew I got it wrong the first time I drew it because I couldn't just tag three methyl groups to carbon 7. The only way I think I can do that is by adding a cyclobutanyl group! But, I'm afraid that might be misrepresenting the given formula. I think a cyclobutanyl group included would have the condensed formula written as CH3CH2OC(O)CH2C(C(CH2)3)CH(CN)CHO.

(CH₂)₃ is just three -CH₂- groups in line.

 

[Dr Transport]

if memory serves me correctly, the CC is actually C=C and the (CH_2)_3 is
CH_2CH_2CH_2

 

[Borek]

the CC is actually C=C

Close, but no, it is not a double bond.

memory failed me...

Thanks for your help! I think I got it now!

Yes, looks like you are right.

@Dr Transport - you were close, it was just C\equiv C, not C=C.
