Question:

In the structure of ClF3, the number of lone pairs of electrons on central atom Cl is:

four

one

two

three

Solution:

In the structure of ClF3, the number of lone pairs of electrons on central atom Cl is two. Cl has 7 valence electrons out of which 3 are involved in bond formation with 3 F atoms. 7 - 3 = 4 valence electrons remains in the form of 2 lone pairs of electrons.
