1dep in fpt depends on Kf of solvnt whch depnds on nature of solvnt.
guess its corrct
13"i" depends on the Degree of dissociation.
TriFluoro one will ionise the MaX. 'coz of the stabilisation of the -ve charge acquired,, due to gr8test -I effect.
1correct avik....
actually for monoprotic acid like acetic acid and its derivatives...
i=1+(alpha)
hence (alpha) proportional to acidic character proportional to depression in freezing point.....(it can be any colligative property!!!)
1yup since ΔTf = Kf mi
i = vant hoff's factor , m = molality , Kf to aaap jante hi hoge
and i =[1 + (y-1)x] where x is degree of dissociation and y is the no. of product molecules yield by 1 mole of reactant [1]
