What is the shape of the I B r 2 - ion?
Options
- ALinear
- BBent shape with bond angle of about 90 °
- CBent shape with bond angle of about 109 °
- DBent shape with bond angle of about 120 °
Correct answer
A. Linear
Step-by-step solution
the shape of the I B r 2 - ion is Linaer I B r : X = 2 + 1 2 [ 7 - 2 + 1 ] = ( 2 σ -bonds + 3 lone pairs) s p 3 d -hybridisation shape → Linear.
