The number of lone pair of electrons in the central atom of SCl2, O3, CIF3 and SF6 are 2, 1, 2 and O respectively
Their structures are as,
So, the correct option is (B): 2, 1, 2 and 0.
Such a group of atoms is called a molecule. Obviously, there must be some force that holds these constituent atoms together in the molecules. The attractive force which holds various constituents (atoms, ions, etc.) together in different chemical species is called a chemical bond.
There are 4 types of chemical bonds which are formed by atoms or molecules to yield compounds.
