Cоnsider the spectrum аnd аnswer the fоllоwing: (note: the unlаbeled signal at ~6ppm is a multiplet) a) Which molecule agrees with the provided 1H NMR spectrum (below)? [nmr] b) Which molecule should have the most deshielded non-aromatic singlet? [nmr1] c) What will be the splitting pattern of the most deshielded non-aromatic signal in molecule 1? [t1] d) Which molecule after undergoing Friedel-Crafts methylation provides a molecular formula of C10H10O but does not show any change in the total number of signals in the 1H NMR, but does show a change in chemical shifts? [FC]
