Chapter 13, Problem 13.31P

For each compound, assign likely structures to the fragments at each $m\text{/}z$ value, and explain

how each fragment is formed.

a. ${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}\text{OH}$: peaks at $m\text{/}z=\text{104, 91}$.

b. ${\text{CH}}_{\text{2}}=\text{C}\left({\text{CH}}_{\text{3}}\right){\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}\text{OH}$: peaks at $m\text{/}z=7\text{1, 68, 41, 31}$.
