From each group of three molecules, choose the one whose structure is most consistent with the proton-decoupled

Question:

From each group of three molecules, choose the one whose structure is most consistent with the proton-decoupled ¹³C NMR data. Explain your choices.

(a) CH₃(CH₂)₄CH₃, (CH₃)₃CCH₂CH₃, (CH₃)₂CHCH(CH₃)₂; δ = 19.5 and 33.9 ppm.

(b) 1-Chlorobutane, 1-chloropentane, 3-chloropentane; δ = 13.2, 20.0, 34.6, and 44.6 ppm.

(d) ClCH₂CHClCH₂Cl, CH₃CCl₂CH₂Cl, CH₂ = CHCH₂Cl; δ = 45.1, 118.3, and 133.8 ppm.
