Which of the following is not a correct statement ?
Which of the following is not a correct statement ?
Updated On: Oct 13, 2023
- The electron-deficient molecules can act as Lewis acids
- The canonical structures have no real existence
- Every AB5 molecule does in fact have square pyramid structure
- Multiple bonds are always shorter than corresponding single bonds
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Not every AB5 molecule has a square pyramid structure. While some AB5 molecules, such as phosphorus pentachloride (PCl5), do have a square pyramid structure, others may have different structures depending on the atom involved and its geometry. For example, SF5Cl has a trigonal bipyramidal structure, not a square pyramid. The actual structure depends on the specific molecular geometry and the arrangement of atoms and lone pairs around the central atom.
So, the correct option is (C): Every AB5 molecule does in fact have square pyramid structure

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
