    thank you so much for this video, sir. i has a hard time understanding this subtopic in our transition element chapter, especially predicting the colour. but after listening to your explanation, i can now grasp this concept

    At 4:15, will the electron not transition back to its ground state afterwards? Then it'll emit the orange light and the net effect will be white?

    • @ChemistryGuru
      @ChemistryGuru  3 ปีที่แล้ว

      that's a very good observation. it is true that electron will lose energy, emit the same orange light and go back down to lower d level for subsequent d-d transition.
      However the emission will be dispersed in all directions, so the intensity of orange light is much lower as compared to the rest of the light that travel to our eyes, so we will not be able to detect the orange light.
      For A Level syllabus we do not need to include this in the answer, so we just need a very simplified version to explain the colours of transition metals

    mind if i ask why is it that only orange light is absorbed by the electron?
    why is it that other energy levels / colours of light are reflected?
    i.e. why cant the electron just absorb something of even higher energy and maybe have both the electrons promoted to the higher part? (not just one high and one low)

    Exremely useful Mr Puah!
    Btw, i have a question on the drawing of the dot and cross diagram for a carbon monoxide molecule. I m trying to use one of your videos to draw but m still having difficulty to draw.

    • @ChemistryGuru
      @ChemistryGuru  6 ปีที่แล้ว +10

      Hi for carbon monoxide C needs 4 electrons from O but O only needs 2 electrons from C. So what O will do is form a double bond with C, plus an additional dative bond from O to C.
      So in total we have a triple bond in carbon monoxide, one of which is a dative bond from O to C.
      Hope this clarifies 😄

    But FeSO4 is green colour, this is not a complex compound?

  • @Ayana781
    @Ayana781 4 ปีที่แล้ว

    In my textbook there is example of
    [Ti(H2O)6]+3 and the information given is 'it absorbs 520 nm '(which is nearly green region ) so according to your wheel we get red color but the transmitted color of complex is said as violet
    How ?

    • @ChemistryGuru
      @ChemistryGuru  4 ปีที่แล้ว +3

      In general red is the complementary colour of green, but it is possible that the wavelength of 520nm is close to the green- yellow region, so the colour will then be red-violet region (directly opposite the green-yellow boundary). Remember the boundaries we draw are just guidelines as there will be a gradual change of colour and there is no clear boundary between them.

  • @theone3054
    @theone3054 4 ปีที่แล้ว

    really good explantion. I'm just slightly confused on one thing, why do different ligands and different ions produce different colours? Is there a pattern?

    • @ChemistryGuru
      @ChemistryGuru  4 ปีที่แล้ว +3

      different ligands and different oxidation state of the transition metal will change the energy gap between d orbitals and d* orbitals.
      This means a different colour which corresponds to a different energy will be absorbed and we see a different complementary colour that is not absorbed.
      Therefore there will be a change in the colour of the transition metal compound/complex when there is:
      1. change in oxidation state
      2. change in ligands
