Question

Given the following data, determine the molecule.
Homework #3 M

Answer 1

Answer #1

The molecular ion peak (M⁺) corresponds to m/z = 88

There is a peak at m/z = 73

88-73 = 15 corresponds to CH₃-fragment.

There is a peak at m/z = 56

73-56 = 17 corresponds to OH-fragment.

The base peak at m/z = 43 corresponds to the propyl fragment (CH₃CH₂CH₂).

The peak at m/z = 29 corresponds to the CH₃-CH₂ fragment.

Therefore, the structure of the molecule can be written as follows.

CH₃-CH₂-CH₂-CH(OH)-CH₃
