Mass spectrum of pentane contains fragmentation peaks: 15, 29, 43, Please show fragmentation structures of pentane which corresponding with signals founded in spectrum I T ETTCE

Answer 1

1. In oure structure there is amide functional group so it is showing N-H streach at 3300-3500cm^-1. And carbonyl streach at around 1715cm^-1.

2. Fragments of pentane are CH3CH2CH2. m/z is 43

CH3-CH2. m/z is 29

CH3. m/z is 15
