$AlCl_3$ is an electron-deficient compound,but $AlF_3$ is not. This is because
- Aatomic size of $F$ is smaller than $Cl$,which makes $AlF_3$ more covalent
- B$AlCl_3$ is a covalent compound,while $AlF_3$ is an ionic compound
- C$AlCl_3$ exists as a dimer,but $AlF_3$ does not
- D$Al$ in $AlCl_3$ is in $sp^3$ hybrid state,but $Al$ in $AlF_3$ is in $sp^2$ hybrid state
