Look for fragmentation that results in a cation with a positive charge shared by 2 atoms?
OH CH CH2CHCH2CHCH3 CH3CH2CHCH2CHCH3 Hmo m/z (102 18) Notice that alkyl halides, ethers, and alcohols after forming a molecular ion by losingu lone-pair electron-have the following fragmentation behaviors in common: i. A bond between carbon and a more electronegative atom (halogen or orygen breaks heterolytically and the electrons stay with the more electronegative atom. 2. A bond between carbon and an atom of similar electronegativity (carbon, chlorine or hydrogen) breaks homolytically. 3. The bonds most likely to break are the weakest bonds and those that lead to forma tion of the most stable products. (Look for a fragmentation that resolts in a cab with a positive charge shared by two atoms.) PROBLEM 14 is responsible for this peak' Primary alcohols have a strong peak at muz 31. What fragment Ketones knockin A ketone generally has an intense molecular ion peak that is formed by a lone-pair electron The molecular ion fragments homolytically at the cation with a adjacent to the C o bond because this cleavage results in formation o
