Back1,4-dichlorobenzene is used as an insecticide and has the formula C6H4Cl2. What would be the approximate relative heights of M, M+2, and M+4 peaks. For simplicity assume that all carbon atoms are 12C and the 35Cl:37Cl ratio is 75:25.
Propose the number of carbons for a compound that exhibits the following peak in its mass spectrum:
(M)+• at m/z = 72, relative height = 38.3% of base peak
(M+1)+• at m/z = 73, relative height = 1.7% of base peak
Predict the approximate height of the (M + 1) peak for the molecule icosane, molecular formula C20H42.
