Describe the general trends in the following properties of the element

1.	Describe the general trends in the following properties of the elements in Groups-13 Nature of halides
Answer» Solution :NATURE of Halides : These ELEMENTS react with halogens to form trihalides (EXCEPT : `TI, I_3`) `2E_((s)) + 3X_(2(g)) to 2EX_(3(s))` [X=F, Cl,Br,I] Halides of Boron and Aluminum are electron deficient and act as Lewis acids. Lewis acidic character of halides of boron decreases in the following order. `BI_3 gt B Br_3 gt BCl_3 gt BF_3`
