1) Which of these choices best describes the interpretation of a 1H NMR spectral peak that was recorded as 1.85 (2H, t)? The underlined hydrogen atom is intended to be the one producing the peak that we are interpreting. CH-CH2 CH2-CH2 CH3-CH2 CH2-CH2-CH2 CH3-CH2-CH3 None of these interpretations describes this peak. 2) What would be the partial interpretation (concerning the number of chemically equivalent hydrogen atoms in a molecule) of a doublet which integrates for 1 H and is located at...
