Which of the following statements is correct about the geometry of a molecule?

 

Option: 1

The geometry of a molecule is always regular if all the hybrid orbitals after overlapping contain shared pair of electrons.
 


Option: 2

The geometry of a molecule is distorted to some extent if the central atom is surrounded by one or more orbitals containing lone pairs of electrons in the valency shell.


Option: 3

The presence of one or more orbitals with lone pairs affects the bond angle to some extent due to repulsion between lone pair (pairs) with bonded pair.
 


Option: 4

All of the above.

The geometry of a molecule is always regular if all the hybrid orbitals after overlapping contain shared pair of electrons. However, the geometry of a molecule is distorted to some extent if the central atom is surrounded by one or more orbitals containing lone pairs of electrons in the valency shell. This is because the presence of lone pairs of electrons causes repulsion between the lone pairs and the bonded pairs, which distorts the geometry of the molecule.
