The following 1H NMR signals are for three molecules with ether functional groups. All thesignals are singlets (single, sharp peaks). Propose structures for these compounds. (a) C3H8O2,d 5 3.3 and 4.4 ppm (ratio 3 : 1); (b) C4H10O3, d 5 3.3 and 4.9 ppm (ratio 9 : 1); (c) C5H12O2,d 5 1.2 and 3.1 ppm (ratio 1 : 1). Compare and contrast these spectra with that of1,2-dimethoxyethane (Figure 10-15B).
