on a planet where FH is liquid dont you think life would adept its chemicals to not react with it if it didnt "want" it to happen? anyhow I found a list of how polar the molecules are:
HF 1,91
HCl 1,05
HBr 0,8
HI0,42
H2O 1,84
H2O2 2,12
NH3 1,48
SO2 1,63
NO 0,16
NO2 0,4
CO 0,1
CH3OH 1,7
this is in debyes
