Interpretation Introduction

Interpretation: The formula for the dioxygen difluoride is to be identified from the given options.

Concept introduction:

Naming of molecular binary compounds (two element compounds),

The binary compounds of hydrogen with nonmetals are named as hydrogen followed by nonmetals name in ‘ide’ form (add ‘ide’ into stem of the name).

The binary compounds formed by combination of group 4A-7A elements are named as putting the first name as early group elements and last name as late group element in ‘ide’ form, but oxygen and noble gases are exceptional. The more than one number of an element is named by adding prefix as “di-, tri-, tetra-, penta- and so on.
