Molecular abundances and D/H ratios in the disk at t = 0.5tacc (solid lines) and t = tacc (dashed lines) as functions of radius in our fiducial model. Top: vertically averaged abundances of H2CO ice, CH3OH ice, and the sum of icy organics with respect to H2O ice. Bottom: the D/H column density ratios of formaldehyde ice, methanol ice, icy organics, and water ice. Arrows on the right-hand margin indicate the values at the onset of collapse.
