25 CHAPTER 2 ALKANES SOLUTIONS TO TEXT PROBLEMS 2.1 A carbonyl group is C ? O. Of the two carbonyl functions in prostaglandin E 1 one belongs to the ketone family, the other to the carboxylic acids. 2.2 An unbranched alkane ( n -alkane) of 28 carbons has 26 methylene (CH 2 ) groups Fanked by a methyl (CH 3 ) group at each end. The condensed formula is CH 3 (CH 2 ) 26 CH 3 . 2.3 The alkane represented by the carbon skeleton formula has 11 carbons. The general formula for an alkane is C n H 2 n 1 2 , and thus there are 24 hydrogens. The molecular formula is C
