Draw all the resonance Lewis structures of C l O 3 and identify the bond order of the chlorine-oxygen bonds. (a) Draw Lewis formulas of all possible resonance forms. In short, now you have to find the formal charge on nitrogen (N) atom, oxygen atom (O) as well as chlorine (Cl) atom present in the NO2Cl molecule. Sorry, I got confused which was the central atom, I meant to say "with one of the oxygens and not with CHLORINE". If we compare the electronegativity values of nitrogen (N), oxygen (O) and chlorine (Cl) then the nitrogen atom is less electronegative. In NOCl, A is Nitrogen, we have one O and one Cl around Nitrogen, n = 2, and there are two lone electrons i.e. What is the shape of this molecule? Either way, everything has a full octet, so I don't know why putting a double-bond with one of the oxygens is considered "most reasonable". Observing NO2Cl, we find the variance in electronegativity between the 2( N-O) bond directs the dipole moment towards the oxygen atom. It has 6 valence electrons. b. The bond angle is 120 and the bond length between N-Cl is 1.83 and that between N-O is 1.21 . Polarity refers to the distribution of the electric charge between the constituent atoms comprising the molecule. Since nitrogen is less electronegative than oxygen and chlorine, assume that the central atom is nitrogen. Valence electrons given by oxygen atom: Oxygen is group 16 element on the periodic table.
