Question

question 38 this shows a pair of electrons in a covalent bond between two atoms represented as a line a. structural formula b. lewis dot diagram c. space filling model d. molecular formula

Explanation:

A structural formula represents covalent - bonded atoms with lines for bonds. A Lewis Dot diagram shows valence electrons as dots. A space - filling model shows the 3D shape of a molecule. A molecular formula only shows the types and numbers of atoms. Since a line representing a pair of electrons in a covalent bond is characteristic of a structural formula.

Answer:

a. structural formula
