NCERT Class XI Chemistry The p-Block Elements Solutions

Question : 4

Total: 38

Consider the compounds, BCl3 and CCl4. How will they behave with water ? Justify.

Solution:

BCl3 is an electron deficient compound. Also, it has an empty unhybridised p-orbital which can accept electrons. In presence of water, BCl3 hydrolyses and forms B(OH)3.

But, when CCl4 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.
CCl4+H2O → No reaction
