Quizplus · Accepted Answer

Pentyl alcohols, also known as amyl alcohols, have the formula C5H11OH. There are eight structural isomers: 1-pentanol, 2-pentanol, 3-pentanol, 2-methyl-1-butanol, 3-methyl-1-butanol, 2-methyl-2-butanol, 3-methyl-2-butanol, and 2,2-dimethyl-1-propanol. Among these, 2-pentanol, 3-pentanol, 2-methyl-1-butanol, 3-methyl-1-butanol, and 3-methyl-2-butanol have chiral centers and thus each can exist as a pair of enantiomers, adding five more stereoisomers to the count. Therefore, the total number of pentyl alcohols, including stereoisomers, is 13.
