According to the general rule barring some exceptions, the element having the least electronegativity value takes the central position. The bond between atoms and lone pairs of electrons that is present in the molecule. Nitrogen is the least electronegative, we'll put that at the center, put the Oxygens on either side, and we'll put the Chlorine on top. The average N-O bond order is?A) 3, 4/3B) 2, 3/2C) 3, 3/3D) 2, 4/3E) 1, 3. For more practice and better understanding, you can try other lewis structures listed below. In order to minimize this repulsive tendency, the atoms go farther away from each other and try to stabilize the molecular structure. b. 1. You can see the 5 valence electrons present in the nitrogen atom as shown in the above image. d. What is the S-O bond order? National Library of Medicine. Now, you can see in the above image that the oxygen atoms and chlorine form an octet. For example a vulnerable one would be a single bond to be a double bond and so on into the to john lewiS structures that the first determined number of . Hence the valence electrons present in chlorine is 7. The degree of this type of repulsion depends on the EN of X. Hydrogen is the best EN.
