The mass spectrum of an alcohol was found to contain majyr:mkc;fgpc /fs *4 k lg5.say1(3ncf or peaks i3nly5u/m y: uun.qm4 at m/z 102, 57, 4/myiy .35nuu u:qmnland 45.
Which of the following compounds could this spectrum belong to?
A. 2,3-dimethylbutan-2-ol
B. 3,3-dimethylbutan-2-ol
C. 2-methylpentan-1-ol
D. Hexan-2-ol
参考答案: B
本题详细解析:
Explanation: All four compounds have the molecular formula $C_6H_{13}O$ and so will produce a molecular ion peak at m/z 102. Fragmentation will result in a peak at 57 for $C(CH_3)_3^+$ and a peak at 45 for $CH_3CHOH^+$ with 3,3-dimethylbutan-2-ol.
