Which pair of atoms forms a nonpolar covalent bond?a) C

Solution 8SAQ Step 1 of 5 The difference of electronegativity between two elements allows us to know if two atoms are bonded with an ionic, non-polar covalent bond or polar covalent bond. If EN> 1.9 we have an ionic bond If 0.4< EN < 1.9 we have a polar covalent bond. In this case, the two atoms will share the electrons unequally, thus assuming a fractional negative charge (the atom having the higher electronegativity value) and the other a positive charge (the atom having the lower electronegativity value). If 0 < EN < 0.4 we have a non-polar covalent bond. In this case, the two atoms will share the electrons equally. We are going to demonstrate that the correct answer is a), by considering the differt electronegativity values of every couple
