    Hi everyone,

    I'm having a bit of trouble understanding one bit of mass spectrometry (to do with mass spectra of organic compounds).

    I understand that for molecules like Cl2, an electron is knocked off the molecule producing a positively charged Cl2+ ion. This ion fragments into Cl+ ions of mass 35 and 37 that pass into the spectrometer and a mass spectrum is produced showing peaks at 35, 37, 70, 72 and 74. But I was wondering if this is the case for organic compounds like pentane? I find the 'chemguide' explanation a bit hard to understand.

    Any help is appreciated!

Do you agree with the proposed ban on plastic straws and cotton buds?
