The source's intended comparison has CHCl₃ more acidic than CHF₃, attributed to greater polarizability-based stabilisation of the chlorine-substituted conjugate base, choice 1. Silanols are more acidic than analogous tert-alcohols; CO₂ is acidic whereas BeO is amphoteric; NO₂ is acidic whereas NO is neutral. Thus the other displayed orders are reversed. Haloform acidities depend on solvent and decomposition pathways; this is the qualitative comparison intended, not a solvent-independent pK_a value.
