 lone pair-lone pair repulsion is stronger  than bond pair-bond pair and bond pair-lone pair repulsion, because any two lone pairs are closer to each other than a lone pair and a bond pair. Therefore, lone pairs will tend to be farther away from each other than a lone pair and a bond pair, and two bond pairs This will minimize the potential energy, which in turn will give greatest possible stability.
