Answer:
The option (e) None of the choice are correct.
Explanation:
To find [tex]\frac{m}{z}[/tex] ratio in mass spectrometer,
We start calculating from the first option
(a)
[tex]CH_{3}- CH_{2}- OH[/tex]
We know mass of carbon [tex]m= 12[/tex] and atomic number of carbon [tex]Z = 6[/tex]
After calculating we come up with,
[tex]\frac{m}{z} = 46[/tex]
Therefore option (a) is incorrect.
(b)
[tex]CH_{3} -CH_{2}- NH_{2}[/tex]
After calculating we come up with,
[tex]\frac{m}{z} = 45[/tex]
Therefore option (b) is incorrect.
(c)
[tex]CH_{3}- CH_{2}-CH_{3}[/tex]
[tex]\frac{m}{z} = 44[/tex]
Therefore option (c) is incorrect.
(d)
[tex]CH_{3}- CH=CH_{2}[/tex]
[tex]\frac{m}{z} = 42[/tex]
Therefore option (d) is incorrect.
Therefore, the option (e) is correct for this problem
