Question

What is the shape of the $IBr_{2}^{-}$ ion?

• A. Linear
• B. Bent shape with bond angle of about $90^\circ $
• C. Bent shape with bond angle of about $109^\circ $
• D. Bent shape with bond angle of about $120^\circ $

Answer 1

Answer: (A)

the shape of the $IBr_{2}^{-}$ ion is Linaer

$IBr:X=2+\frac{1}{2}\left[\right.7$ -bonds + 3 lone pairs) $\text{s} \text{p}^{3} \text{d}$ -hybridisation shape $ \rightarrow $ Linear.
