Consider the compounds, `BCl_(3)" and "C"C"l_(4)`. How will they behave with water ? Justify.

Text Solution

Verified by Experts

B atom in `BCl_3` has only six electrons. Thus, `BCl_3` is an electron-deficient molecule and accepts a pair of electrons donated by water. Therefore, when treated with water, `BCl_3` undergoes hydrolysis to form boric acid and HCI.
`BCl_3 + 3H_2 O to H_3 BO_3 + 3HCl`
On the other hand, C atom in `C Cl_4` possesses an octet and has no tendency to accept or donate a pair of electrons. Hence, it does not react with water.
