Hexane,C₆H₁₄,would have which of the following fragments in its mass spectrum? m/z I 29 II 43 III 57 A)I B)II C)III D)All of the choices are correct.

Question

Quizplus · Accepted Answer

Hexane has a molecular formula of C6H14. 
Ions at m/z 29 and 43 would likely result from cleavage of a C-C bond within the molecule, generating the CH3+ and CH3CH2+ fragments, respectively. 
An ion at m/z 57 would likely result from cleavage of two adjacent C-C bonds, generating the CH3CH2CH2+ fragment. Therefore, all three fragments (I, II, III) would be present in the mass spectrum of hexane.
