THe above spectrum corresponds to CH3CH2CH2OCH2CH2CH3
Molecular Formula: C6H14O
THe 1H NMR shows a triplet at 1 ppm corresponds to CH3 protons because of the adjacent CH2 group. A multiplet is observed at 1.8 ppm because of the adjacent CH3 and CH2 groups. The triplet at 3.3 ppm is downshielded because of the presence of Oxygen group and adds up to 2 proton.
The IR spectrum did not show the presence of OH stretching or carboxylic group (absent in 13C as well). The 3000 cm-1 corresponds to alkyl stretching groups.
