<span>Electrons in a nitrogen-phosphorus covalent bond are not shared equally because nitrogen and phosphorus do not have the same electronegativity. The atoms spend more time around the most electronegative atom nitrogen.</span>
The empirical formula for the unknown compound would be: C2H4O (2 molecules of Carbon, 4 molecules of Hydrogen, and 1 molecule of Oxygen)
The correct answer is D
a polymer is a substance made up of large molecules with repeating sub units called monomers.
A is incorrect because its a ring structure which means it cannot form the long chain that is exhibited by polymers.
B is incorrect because the double bonds will cause saturation, hence no monomer can bond to another monomer to form the large molecule.
C is incorrect because the large molecule has repeating sub-units hence only specific types of molecules can be present, and it is usually carbon and hydrogen.
