Abundances for different molecule families (a–g) as described in Sect. 4. The blue and orange bars indicate the abundances of core and envelope components, respectively. The hatched bars indicate abundances in the hot core of Sgr B2(N) with respect to H₂, derived by Neill et al. (2014). Since the distinction between ortho and para was not done by Neill et al. (2014), we compare theabundances of the ortho and para molecules with the unresolved results of Sgr B2(N).
