Question

Find out the similarities between $I_{2}C{l}_6$ and $A{l}_{2}C{l}_6$.

• A. Both have $3C-4e^{-}$ bond
• B. Both have $s{p}^3$- hybridization for the central atom
• C. Both are nonplanar
• D. All are correct

Answer 1

The correct option is A Both have $3C-4e^{-}$ bond

A) Both $I_{2}C{l}_6$ and $A{l}_{2}C{l}_6$ have $3C-4e^{-}$ bonds. Hence, option A is correct.
B) In $I_{2}C{l}_6$, the central $I$ atom undergoes $s{p}^3{d}^2$ hybridization and in $A{l}_{2}C{l}_6$, the central $Al$ atom undergoes $s{p}^3$ hybridization. Thus, the option B is incorrect.
C) $I_{2}C{l}_6$ is planar and $A{l}_{2}C{l}_6$ is non planar. Thus, the option C is incorrect.
