Question
Which of the following, not a correct statement?
-
The electron -deficient molecules can act as Lewis acids
-
The canonical structures have no real existence
-
Every AB5 molecules does, in fact, have square pyramid structure
-
Multiple bonds are always shorter than corresponding single bonds
Solution

Every AB5 molecules does, in fact, have square pyramid structure
Every AB5 molecule does not, in fact, have square pyramidal structure but AB5 molecules have trigonal bipyramidal structures due to sp3d hybridisation.
