Homework Answers
Solution:
The molecular formula will be : CH3CH2CH2Cl
Compound is : Propyl chloride
Explanation:
The intersities of isotopic peaks of Cl-35 and Cl-37 are in the ratio of 3 : 1.
The intensities of isotopic peaks of C-12 and C-13 are in nearly 49 : 1.
1) The m/z = 78 is due to C-12 and Cl-35. (CH3CH2CH2Cl)
2) The m/z = 79 is due to C-13 and Cl-35
3) The m/z = 80 is due to C-12 and Cl-37
4) The m/z value of 81 is due to C-13 and C-37.
Therefore,
Structure will be : CH3CH2CH2Cl
