Which of the following molecule have bond as well as planar geometry ?

Options:

Answer:
C
Solution:

A 3-center-4-electron (3c-4e) bond involves three atoms sharing four electrons. Planar geometry means all atoms lie in the same plane.

 

In I₂Cl₆, the central iodine atoms are hypervalent, forming 3c-4e bonds with bridging chlorine atoms. The molecule has a planar D₂h geometry.

 

Al₂Br₆ and Al₂I₆ have 3c-2e bonds and are non-planar. (AlH₃)n is polymeric.

 

The final answer is C.
