    If you have symmetry and one environment is mirrored elsewhere in the molecule, just look at one side for the splitting pattern.

    Eg if you had CH3-CH2-O-CH2-CH3 it is symmetrical. So only 2 H environments. The CH3 peak would be a triplet due to the neighbouring CH2, and the CH2 would be a quartet due the neighbouring CH3
    But in this case, the two CH2 groups would be in the same environment (peak integration:4), and the two CH3 groups will also be in the same environment (peak integration:6)
    Would the peak representing the two CH2 groups not be split into a septet tho because there is a CH3 group neighbouring each of them (so 6 neighbouring protons in total?)
    And vice versa, the peak representing the two CH3 groups will be a quintet?
    Soz I'm confused af lol

    ch2 would split into quartet right?

    I did a legacy paper and I think the answer said that it can't be split as it can't split itself if that makes sense

    Can carboxylic acids be reduced by NABH4 aswell?

    No my splitting pattern description was correct. And integration would be 2:3 not 4:6 as its simplified

    what do I write for bonding and structure for benzene??


    good luck guys btw
    Overlap of p orbitals = pi bonds
    Overlap of more land 2 carbons=delocalised electrons
    Benzene has a delocalised ring system
    The 6 electrons are shared over 6 carbons give a low electron density
    Benzene is planar, with bond angles of 120 degrees
    That's all I can think of

    Split by the ch3 into a quartet

    But not split by the ch2 as the env is identical

    Ah I forgot about the CH3 thanks!

    Can't be reduced by NaBH4, but can be reduced by other reducing agents

    quick question when oxidising an aldehyde to a carboxylic acid do you have to heat under reflux???

    How is everyone feeling about this exam? I've being doing some last minute questions from the revision section on physics and maths tutor and it seems to be going pretty well, I think tomorrow I may go through a couple more NMR q's just before the exam as it seems to always be worth a ton of marks.
