I had this confusion related to nomenclature of halo substituted compounds.

Why is it that 1-Bromo-3-methylbut-2-ene is named like that and not as 2-(1-bromomethyl)but-2-ene? why do we prefer the carbon chain including the carbon attached to the bromine and not the chain including the carbon of the methyl group?

Which IUPAC rule was used in making this preference between those two carbon chains of equal length?
