Proton NMR: why does this appear as a multiplet?

  1. Jan 31, 2013 #1
    1. The problem statement, all variables and given/known data

    It asks you to identify the shift and nature of the protons in the molecule.

    Picture:

    2. Relevant equations

    none

    3. The attempt at a solution

    I cannot understand what makes C a multiplet. I suppose I am confused about the concept of a multiplet in general.

    Two d protons and single b proton. Together they should yield doublet of triplets (or triplet of doublets).

    why is D not a multiplet ?
