Lewis structure
Draw the Lewis structure of nitrosyl chloride. Start by drawing the overall structure of the molecule, ignoring potential double and triple bonds: Count the total valence electrons of the chlorine (n_Cl, val = 7), nitrogen (n_N, val = 5), and oxygen (n_O, val = 6) atoms: n_Cl, val + n_N, val + n_O, val = 18 Calculate the number of electrons needed to completely fill the valence shells for chlorine (n_Cl, full = 8), nitrogen (n_N, full = 8), and oxygen (n_O, full = 8): n_Cl, full + n_N, full + n_O, full = 24 Subtracting these two numbers shows that 24 - 18 = 6 bonding electrons are needed. Each bond has two electrons, so in addition to the 2 bonds already present in the diagram add 1 bond. To minimize formal charge oxygen wants 2 bonds and nitrogen wants 3 bonds. Identify the atoms that want additional bonds and the number of electrons remaining on each atom: Fill in the 1 bond by pairing electrons between adjacent highlighted atoms: Answer: | |
