Which of the following compounds contains a nonpolar covalent bond-

Question

MgF2

NaCl

H2O

N2

Answer 1

A covalent bond is a bond created between non-metals 

, are those elements that reside from the "right side" of the periodic table.  From the choices provided, we see that only one answer choice fits this description: choice N2

 

With this homeo-covalent bond, the charge of both nitrogens will essentially "cancel out" or have "no" pull, which fits the definition of nonpolar. 

Answer 2

Hi Christy,

Since atoms of N have identical electronegativities, their bond is completely covalent, so N₂ is the answer.
