NMR Splitting Butane

  1. Jan 10, 2012 #1
    1. The problem statement, all variables and given/known data
    Butane, CH3CH2CH2CH3
    has two proton environments
    would the splitting be 3, 6 OR 3,4


    2. Relevant equations



    3. The attempt at a solution
    The 3 splitting would be because the CH3 group is next to a carbon with 2 hydrogens (n+1 --> 2+1 = 3)

    Now the 6 would be because both CH2 groups neighbour a CH3 and CH2 group. (n + 1 --> 5+1 --> 6)

    The 4 would be because both CH2 groups neigbhour a carbon with three hydrogens (n+1--> 4)
    I am not sure if splitting is induced if two CHEMICALLY IDENTICAL groups are next to each other. I know splitting occurs if the neighbouring carbon contains hydrogens BUT IF THE TWO GROUPS ARE IDENTICAL X-CH2-CH2-X then would the splitting be 6 or would it be 4

    thanks
