Homework Help: Organic chem: draw this in line angle structure

  1. Sep 24, 2017 #1
    1. The problem statement, all variables and given/known data
    Draw this formula in line angle structure. CH3CH2OC(O)CH2CC(CH2)3CH(CN)CHO.

    2. Relevant equations
    None.

    3. 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.

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

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

    Yes, looks like you are right.

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