Chloroform is more acidic than fluoroform. Explain.

Text Solution

Verified by Experts

`CF_(3)^(Theta)`, the conjugate base of fluroform `(CHF_(3))`, is stabilised by - I effect of 3 F - atoms. But `C CI_(3)^(Theta)` , the conjugate base of chloroform `(CHCI_(3))`, is relatively more stabilised by somewhat weaker - I effect of 3 - CI - atoms along with d - orbital resonance (CI has vacant d - orbital). So chloroform is more acidic than fluroform.
