X Compounds No Solvent!In the absence of a solvent, the acidity of HX compounds is related to the ease of dissociation into ions, which defines the proton affinity: HX(g) ÷ H +(g) + X –(g) ∆H = proton affinity • Lower ∆H means greater acidity of HX and lesser basicity of X –.! Group trend — Acidity increases with increasing size of X.
