We compute important ratios between decay widths of some exclusive two-body\nnonleptonic and semileptonic B decays, which could be test of factorization hy-\npothesis. We also present a summary of the expressions of the decay widths and\ndifferential decay rates of these decays, at tree level, including l = 0\n(ground state), l = 1 (orbitally excited) and n = 2 (radially excited) mesons\nin the fi- nal state. From a general point of view, we consider eight\ntransitions, namely H \→ P, V, S, A, A, T, P (2S), V (2S). Our\nanalysis is carried out assuming factorization hypothesis and using the WSB,\nISGW and CLFA quark models.\n
