Which of the following two are isostructural ?A. `XeF_(2), IF_(2)`B. `NH_(3), BF_(3)`C. `CO_(3)^(2) ,SO_(3)^(2)`D. `PCl_(5), ICl_(5)`. |

Answer» Correct Answer - A `XeF_(2)` is a linear molecule (Xe is `sp^(3)d^(2)` hybridised with three equitorial positions by lone pairs). `IF_(2)` is also a linear molecule as explained below. No of electron around I = 7 + 2 + 1 (due to -ve charge) = 10 There, I is `sp^(3)d^(2)` -hybridised. There are 3 lone pairs and 2 bond pairs. Thus, its structure is similar to `XeF_(2)`. |
