An illustration depicts the various carbocations formed from the fragmentation of pentane. The structure of pentane is showed within square brackets with a plus symbol superscript. The structure reads C H 3-C H 2- C H 2 - C H 2 - C H 3. Four carbocations are formed and their structures are as follows: (M-15) - The structure of the first fragment shows a 4-carbon chain with a positive charge on the first carbon atom. The other fragment is methyl group with a lone electron. (M-29) - The structure of the first fragment shows a 3-carbon chain with a positive charge on the first carbon atom. The other fragment shows an ethyl group with the second carbon atom having a lone electron. (M-43) - The structure of the first fragment shows a 2-carbon chain with a positive charge on the first carbon atom. The other fragment shows a propyl group with the third carbon atom having a lone electron. (M-57) - The structure of the first fragment shows methyl group with a positive charge on the carbon atom. The other fragment shows a butyl group with the fourth carbon atom having a lone electron.
