Isomers of C₅H₁₂ Isomers of C₅H₁₁Cl Cl Cl light + + Cl Cl Cl Cl₂ Cl Cl light + + + Cl light 2.40 The DU of C₅H₁₀ = [(2)5 +2 - 12]/2 = 1, so the unknown has one ring or one double bond. All of the carbons of the isomer that gives only one must be identical. The five-membered cyclic alkane is the only isomer that has all of its carbons identical. Cl light C₅H₁₀ C₅H₉Cl F 2.41 From Chapter 1, = (e)(d). Because F is more electronegative than CI, e is larger for CH₃F than for But the C-CI bond C H C H (1.78 Å) is longer than the C-F bond (1.38 Å) so d is H H H H larger for CH₃CI than for 2.42 amine, alcohol, amide, carboxylic acid 24
