Which of the following is not a correct statement?

Options

  1. AMultiple bonds are always shorter than corresponding single bonds
  2. BThe electron deficient molecules can act as Lewis acids
  3. CThe canonical structures have no real existence
  4. DEvery AB ₅ molecule does in fact have square pyramidal structure

Correct answer

D. Every AB ₅ molecule does in fact have square pyramidal structure

Step-by-step solution

The AB ₅ molecule does not have a square pyramidal structure but has a trigonal bipyramidal structure because of s p^3 d hybridisation. Related Theory Benzene exist in canonical structure
