Verified step by step guidance

Identify the longest carbon chain in the molecule. In this case, the longest chain contains five carbon atoms, which makes it a pentane.

Number the carbon atoms in the chain starting from the end closest to the first substituent group. Here, the numbering should start from the leftmost carbon to ensure the lowest possible numbers for the substituents.

Identify and name the substituents attached to the main chain. There are two bromine atoms (dibromo) and three hydroxyl groups (triol) attached to the chain.

Assign the correct locants (position numbers) to each substituent based on the numbering of the carbon chain. The bromine atoms are attached to the first carbon, and the hydroxyl groups are attached to the first, second, and fourth carbons.

Combine the names of the substituents with the main chain name, including the locants, to form the complete IUPAC name: 1,1-dibromopentane-1,2,4-triol.
