Question

$BeC{l}_2$ and $IC{l}_2^{-}$ are linear species. What is the hybridisation of $Be$ and $I$ respectively?

• A. $sp$ and $s{p}^{3}d$
• B. $s{p}^{3}d$ and $sp$
• C. $s{p}^3{d}^2$ and $s{p}^3$
• D. $s{p}^{3}d$ and $s{p}^3$

Answer 1

The correct option is A $sp$ and $s{p}^{3}d$

In $BeC{l}_2$ $Be$ is $sp$ hybridised.
In $IC{l}_2^{-}$, $I$ is $s{p}^{3}d$ hybridised.
