What is the IUPAC name for the compound CH3(CH2)4OH?

The correct IUPAC name for CH3(CH2)4OH is 1-Hexanol. To determine this, we start by identifying the carbon chain and the functional group present.

The molecular formula indicates that there is a straight chain of six carbon atoms, as evident from the CH3 group (a methyl group) and five subsequent CH2 groups. This gives us a total of six carbon atoms, indicating that the compound is a hexanol.

When naming alcohols, the numbering of the carbon chain begins from the end closest to the functional group (in this case, the hydroxyl -OH). Since the hydroxyl group is attached to the first carbon in the chain, it is denoted as 1-Hexanol.

This systematic approach to naming is crucial in organic chemistry, ensuring that the functional groups and the structure of the molecule are both accurately reflected in the name. Thus, the presence of the hydroxyl group at the first position confirms that 1-Hexanol is the correct IUPAC name for the compound.
