Which of the following is not a correct statement?

  1. A
    The electron deficient molecules can act as Lewis acids.
  2. B
    The canonical structures have no real existance.
  3. C
    Every molecule does in fact have square pyramidal structure.
  4. D
    Multiple bonds are always shorter than corresponding single bonds.

Solution & Step-by-step Explanation

type molecules, where the central atom 'A' lacks lone pairs (like ), typically adopt a trigonal bipyramidal geometry ( hybridization) to minimize repulsion, not a square pyramidal structure. Square pyramidal geometry is typically seen in systems (like ).
