<prompt> Ukuhlukaniswa kokuqala kukhombisa ukuthi le yinkanyezi yohlobo lwe-B ekulandelaneni okuyinhloko kwezinkanyezi ezikhiqiza amandla ngokuhlanganiswa kwe-hydrogen entsheni. Kodwa-ke, isigaba sokukhanya se-IVsizophakamisa ukuthi le yinkanyezi engaphansi; okusho ukuthi ukunikezwa kwe-hydrogen entsheni yayo kuyaphelelwa futhi inkanyezi isiqalile inqubo yokuvela kulandelana okuyinhloko. Ayinazo izihlobo ezaziwayo. Ububanzi obulinganisiwe bale nkanyezi, ngemuva kokulinganisa ubukhulu bokufiphala okulungile, bungu-1.02 0.07 mas.  <response>: 101 izinga
