    It is because Cl has a vacant 3d-orbital and it can stabilize the negative charge by the mesomeric effect, which is not the case with F. This is also the reason why CHCl3 is a stronger acid than CHF3.

    Ist one is more stable

    eduncle-logo-app

    In CCl3-, the -ve charge gets delocalised to the vacant d-orbital of chlorine (known as d-orbital resonance), wheareas no such phenomenon can be exhibited by fluorine in case of CF3- due to absence of any vacant orbital resonance. Hence,ย CCl3(-) more stable than CF3(-).

    eduncle-logo-app

    In flourine there is absence of vacant d orbital so no delocalisation of negative charge.
