Molecular ion peak

m/z 158 = M⁺•

CH3CH2CH2CH2CH2C(=O)OCH2CH2CH3⁺•

Base peak

m/z 56

This is the tallest or most abundance peak, so this is the base peak.

Quote from: amimi on March 07, 2026, 04:15:45 PMThank you!! Wouldn't the COOH be further reduced though in bottom problem? to just sigma bonds

-COOH can be reduced by LiALH4 only.However -CN group can be reduced to -CH2NH2
