Question
Which of the following is not a correct statement?
A.
The electron deficient molecules can act as Lewis acids
B.
The canonical structures have no real existence
C.
Every $$A{B_5}$$ molecule does infact have square pyramid structure
D.
Multiple bonds are always shorter than corresponding single bond
Answer :
Every $$A{B_5}$$ molecule does infact have square pyramid structure
Solution :
Generally, $$A{B_5}$$ molecules have trigonal bipyramidal structure due to $$s{p^3}d$$ hybridisation but in some cases due to presence of lone pair of electrons, its geometry becomes distorted.
