Question

What will be the shape of $IC{l}_2^{-}$ among the following ?

• A. Bent
• B. Trigonal bipyramidal
• C. Linear
• D. Trigonal planar

Answer 1

The correct option is C Linear

$IC{l}_2^{-}$ has two bond pairs and three lone pair, so the steric number of central atom $I$ will be = 2+3=5 and the hybridization is $s{p}^{3}d$. Hence the geometry is trigonal bipyramidal and shape is linear.
