¯_(ツ)_/¯ I was just trying to highlight a fun fact about how they act similarly metabolically.

But since you asked, according to wikipedia, the oral LD50s for acetone and isopropanol (taking average of values for rats, mice, and rabbits) are 4713 and 3655 mg/kg, respectively. Extrapolating to a 75 kg human, that’s 451 and 349 mL for a 50/50 shot at permanent night-night. For comparison, ethanol is ~7300 mg/kg -> 694 mL by the same metric.
