Give hydrolysis product of trihalides of boron family.

Explanation

To find the hydrolysis products of the trihalides of the boron family (Group 13 elements), we will analyze each member of the boron family and their respective trihalides. The members of the boron family include Boron (B), Aluminum (Al), Gallium (Ga), Indium (In), and Thallium (Tl). Their trihalides can be represented as BX3, where X can be Fluorine (F), Chlorine (Cl), Bromine (Br), or Iodine (I).

### Step-by-Step Solution:

1. **Identify the Trihalides:**
- The trihalides of the boron family can be represented as:
- Boron: BF3, BCl3, BBr3, BI3
- Aluminum: AlF3, AlCl3, AlBr3, AlI3
