You need to provide $pK_a$ for hypobromous acid.

We wish to assess the equilibium:

$KOBr(aq) + H_2O(l) rightleftharpoons HOBr(aq) + HO^(-)(aq)$

$K_b=([HO^-][HOBr])/([""^(-)OBr])$

Without the $K_b$ value we are shot birds. You will find $K_a$ in the literature, and this we can use to assess $K_b$ .
