Unformatted text preview: carbon that bears the hydroxyl group. ( g ) This alcohol has its hydroxyl group attached to C-2 of a three-carbon continuous chain; it is named as a derivative of 2-propanol. ( h ) The six carbons that form the longest continuous chain have substituents at C-2, C-3, and C-5 when numbering proceeds in the direction that gives the lowest locants to substituents at the f rst point of difference. The substituents are cited in alphabetical order. Had numbering begun in the opposite direction, the locants would be 2,4,5 rather than 2,3,5. 1 2 3 4 5 6 Br 5-Bromo-2,3-dimethylhexane CH 3 CH 3 OH 2-Cyclopentyl-2-propanol cis-3-tert-Butylcyclohexanol OH 2,2,2-Trifluoroethanol CF 3 CH 2 OH 1-Bromo-1,2,2-trichloroethane Cl 2 CHCHBr Cl Cl 3 CCH 2 Br 2-Bromo-1,1,1-trichloroethane CH 3 CH 3 CHCH 2 CH 2 CH 2 OH 4-Methyl-1-pentanol 74 ALCOHOLS AND ALKYL HALIDES...
