When `BCl_(3)` is treated with water, it hydrolyses and forms `[B[OH]_(4)]^(-)` only whereas `AlCl_(3)` in acidified aqueous solution forms `[Al[H_(2)O]_(6)]^(3+)` ion. Explain what is the hybridisation of boron and aluminium in these species ?

Text Solution

AI Generated Solution

To determine the hybridization of boron in \([B(OH)_4]^-\) and aluminium in \([Al(H_2O)_6]^{3+}\), we can analyze the bonding and geometry of each species. ### Step 1: Analyze the Hydrolysis of \(BCl_3\) When \(BCl_3\) is treated with water, it hydrolyzes to form \([B(OH)_4]^-\). 1. **Identify the Valence Electrons of Boron:** - Boron (B) has an atomic number of 5, which means it has 3 valence electrons. ...
