The IUPAC name for this compound, whose condensed chemical formula is C5H11OH, is pentan-1-ol. It’s also called 1-pentanol and n-pentanol (n standing for ‘normal’).
To work out the name of a compound containing a hydrocarbon chain, using the IUPAC rules, you count the number of carbons in the chain, in this case five, so the prefix ‘pent’ is used. There are no double bonds, so without the -OH group, this compound would be called n-pentane, but because this compound has a terminal -OH group, it is classified as an alcohol, so the suffix ‘ane’ is replaced with ‘anol’. The position of the -OH group is determined by giving it the lowest number of attachment possible, so rather than pentan-5-ol, one counts from the opposite end of the hydrocarbon chain, giving its’ attachment as 1.
PS. The prefixes for 1–12 length chain hydrocarbons are good to commit to memory, as are some of the IUPAC naming procedures, which can be found by searching IUPAC naming rules.
