Consider the following reaction
The geometries of 
and 
respectively are
Text Solution
Verified by ExpertsThe correct answer is:
A
The molecular geometry of 
is trigonal planar. In 
, the central atom 
has 6 valence electrons that makes it an electron deficient molecule. 
acts as a Lewis acid as it requires 2 electrons to complete its octet. 
can donate its lone pair to boron. The resulting structure is tetrahedral.
