    Quick tips: Single-bonded oxygen = -1
    Double-bonded oxygen = 0
    ** P is from group 5, it is less electronegative than O. Hence, P = positive(+) formal charge.
    Consider this, since P is from group 5 = + 5. Therefore, the charge reduces by one for each single bond with oxygen. This means, when there are four (4) total single bonds with oxygen, P = +1.
    When there is a double bond + 3 single bonds (5 total bonds), P = 0 charge

    the way you explain everything from the ground up and thoroughly is a godsend, thank you mr. knight. As you said, no more confusion!

    Sorry can you explain NO3-? I'm confused why it has only one double bond instead of 2, it would be more stable if it had 2 double bonds with oxygen

    • @science_exam

      Hello, sorry for the reply(crazy busy). Theoretically, the two double bonds would make sense. However, the highest orbital for nitrogen is 2p. Therefore, 2s and 2p can only account for maximum 8e- ( 2 on 2s and 6 on 2p = 8 maximum e-). N is unlike P that can access the 3d orbital.
      I hope this helps🙏

    Thank you, Mr. Knight! I like how you leave the explanation of the stability factor for the molecule until the end of the discussion. This gives the learner the "why" to the unusual double bonded oxygen at the conclusion. Then when you add in the d orbital with its 10 e-s, this gives us the "how" the stable molecule is accomplished. Will there be resonance structures with this molecule?

    • @science_exam
      @science_exam  Год назад

      You are welcome. There will be resonance, they can be achieved by shifting the double bond around.

    sir So to make the structure stable we have to make anyone of their formal charge zero ?

    • @science_exam
      @science_exam  2 года назад +3

      The total formal charges must be equal to zero. The more zero charges are there on individual atoms, the more stable the structure.

    Not how can phosphorus contain more than 8 but how do you decide to do the double bond. Calculating Formal charge for all possible structures takes so long

    So for all the compounds of phosphorous octect rule doesn't apply bcoz of the d orbital?

    • @science_exam
      @science_exam  3 года назад +1

      The octect rule still apply, but to make the lewis structure stable the d orbital should be considered. Remember, not all of the compounds of phosphorus will need to have 5 total bonds. It really depends on what makes the molecule more stable.
