Question

PART 1: EXAMPLE To receive credit, all handwriting must be CLEAR, NEAT, and CLEAN! Fill in the boxes below for each molecule, as demonstrated in the EXAMPLE. HA i) Draw ALL protons. ii) Label equivalent protons with the same subscript letter, in alphabetical order from left to right or clockwise on the structure when possible (as demonstrated in RED in the EXAMPLE) iii) Indicate splitting by s singlet, d-doublet, t-triplet, q-quartet, m=multiplet, dd=doublet of doublets, AND an arrow pointing to ONE of the protons (as demonstrated in the EXAMPLE). That is, no need for multiple arrows to equivalent protons. iv) For each molecule indicate the degrees of unsaturation and the number of unique signals in the C NMR spectrum. This entire assignment is to be completed independently. Ha Ha He He H4 HA HA He He Hs He HA Chemical Formula: CaH1402 degrees of unsaturation unique 13C 3 signals:

please fill in answers according to instruction. thank you.
