Chapter 13: Q 26. (page 521)

Question:Which compound gives a molecular ion at m/z= 122: $C_{6} H_{5} {CH}_{2} {CH}_{2} {CH}_{3}$ , $C_{6} H_{5} {COCH}_{2} {CH}_{3}$ , or $C_{6} H_{5} {OCH}_{2} {CH}_{3}$ ?

Short Answer

Expert verified

Answer

$C_{8} H_{10} O$ , Molecular ion peak atm/z = 122

Step by step solution

Mass Spectra

The spectroscopic technique used for the identification of a compound based on the mass of the compound is referred to as mass spectroscopy. The spectra obtained from this spectroscopy are referred to as mass spectra.

Structure determination

In mass spectroscopy, the structure is determined on the basis of the mass of the given structure

$C_{9} H_{12}$ , Molecular ion peak at m/z = 120

$C_{9} H_{10} O$ , Molecular ion peak at m/z = 134

$C_{8} H_{10} O$ , Molecular ion peak at m/z = 122
