MASS SPECTRUM.......2-pentanol

Structure: 
IUPAC Name: 2-pentanol

Analysis: C₅H₁₂O MW = 88.15







The spectrum shows a small molecular ion and a small m-1 peak, suggesting the presence of an alcohol (it cannot be an aldehyde since there are no degrees of unsaturation). The m-15 peak represents loss of a methyl group and the m-17 is consistent with loss of a hydroxy radical. For an alcohol, the base peak is often formed by expulsion of an alkyl chain to give the simple oxonium ion R^'CR^''OH⁺; to generate the observed m/e = 45, R^' must be CH₃ and R^' a H.






MS Fragments:


The spectrum shows a small molecular ion and a small peak resulting from loss of a hydrogen atom from the alcohol. Loss of a methyl group gives the m-15 peak and loss of hydroxy radical gives the secondary carbocation at m-17. The base peak, not surprisingly, is formed by expulsion of the alkyl chain to give the simple oxonium ion at m/e = 45.
