sir please explain that Why CHCl3is more acidic than CHF3 ?

Hi !Raju ,

         cl₃c^- is less basic than F₃c^- because florine can disperse charge only by an inductive effect while cl(having 3d orbitals) disperses charge by inductive effect as well as by p PIE -p PIE bonding delocalisation.Florine is a second period element with no 2d orbital.

Hope it’s help you,

All the best !!!!

@ raju 
chf3 when it will be separate into its ions then it will generate cf3- and h+ 
and chcl3 when it will dissociate into ions , it will generate ccl3- and h+ . 
cf3- is not stable by resonance due to the absence of d orbital on F . but ccl3- is stable by resonance due to the presence of d orbital . 
HOPE IT CLEARS YOUR DOUBT 
ALL THE BEST ..
