Question

The maximum number of 180${}^0$ angle possible between $X-M-X$ bond for compounds with $s{p}^3{d}^2$ and $s{p}^{3}d$ hybridization respectively are:

• A. 3,3
• B. 3,1
• C. 1,3
• D. 3,0

Answer 1

Answer: (B)

3,1

1. $s{p}^{3}d$ is $MX5$ kind of geomtery in which two are at axial positions and other at equitorial positions. Hence no. of $X-M-X$ bonds of ${180}^o$ are = 1

2. In $s{p}^3{d}^2$ it is octahederal type geomtery hence there would be 3 bonds with straight ${180}^o$
