IUPAC Name: 1,2-dimethoxyethane 

C4H10O2

. The peak is a triplet, indicating that it corresponds to a CH2. The chemical shift (d 80) suggests that the CH2 is adjacent to an electron-withdrawing group, such as an oxygen, and may be further shifted due to steric effects. - O - CH2-       The peak is a quartet, indicating that it corresponds to a CH3 group. The chemical shift (d 54) suggests that the CH3 is adjacent to an electronegative atom (i.e., oxygen). Note that there are only two peaks in the spectrum, but there are four carbons in the molecular formula. - O - CH3        Analysis : Molecular formula and index of hydrogen deficiency C4H10O2 The index of hydrogen deficiency is zero (no double bonds or rings). Interpret : d (ppm) Multiplicity (n + 1) Indicating 80 triplet - O - CH2 - 54 quartet - O - CH3 The 13C NMR has two peaks, a quartet at d 54 (a CH3) and a triplet at d 80 (a CH2). Since the molecule has four carbons and only two 13C NMR peaks, there must be symmetry. Both peaks are in the regions where carbons next to electronegative atoms occur (oxygen). 10 Best Restaurants in Chinatown Singapore Where to eat in Chinatown Singapore Chinatown Singapore has an excellent variety of restaurants, ranging from outdoor diners where you can sample some of the city’s best street food to places that frequently make lists of the world’s very best restaurants.
