Answer:
Explanation:
From the given information :
The molecular mass m/z of chlorobenzene = 112
Also the isotope of chlorine are:
[tex]^{35}_{17}Cl \ \ and \ \ ^{37} _{17}Cl[/tex] SInce isotopes are atoms with the same atomic number but different mass number .
With an abundance of 3:1
FOr a molecular ion peak; there is need for the presence of [tex]^{37}_{17}Cl[/tex]:;
As such the m/z value of M⁺ = 112 for a molecular ion peak
The approximate abundance at 112 for a molecular ion peak will be:
abundance of 15% × 3
= 15% × 3
= 45%
