$BCl_3$ is an electron deficient compound. Also, it has an empty unhybridised p-orbital which can accept electrons. In presence of water, $BCl_3$ hydrolyses and forms $B(OH)_3$. But, when $CCl_4$ is mixed with water, no reaction takes place because carbon neither has any unhybridised, empty p-orbital where it can accommodate electrons from water nor it has empty d-orbital. $CCl_4+H_2O$ → No reaction
