Question

2) Identify the correct IUPAC name for the following structure. A) 6-bromo-1-cyclopentyl-3,6-dimethylhexane B) 1-bromo-5-cyclopentyl-1,4-dimethylpentane C) 2-bromo-6-cyclopentyl-5-methylhexane D) 5-bromo-1-cyclopentyl-2-methylhexane E) none of the above

Answer 1

2 Option (D): 5-bromo-1-cyclopentyl-2-methyl henome A Br IUPAC Nome: 5-bromo-t-Cyclopentyl-2-methylhexane Since alkyl chain is longer (6-carbons) than the.. cycloalkane (5-Carbons), the cycloalkane will act as a substituent while the alkyl chain must be used as the primary parent chain. * Also the naming of the substituents must be done in alphabetical order so that methys follows the cyclop- -entyl which follows the bromo group while name the substituents. * Bro at position 5 S-bromo * Cyclopentylat position 1- 1-cyclopentyl * CH₃ at position a 2-methyl * parent carbon Chains having 6 Carbons - hexane
