Advanced Higher Chemistry 19 Hybridisation and Molecular Orbitals

Why is methane tetrahedral? Why is it easy to break the first bond in a double bond, but not the second? How do coloured pigments like chlorophyll work? The answer to all of these lies within molecular orbitals and we look at these in this video. Prof Dave probably has a more complete explanation here    • Examples of s-p Mixing in Molecular Orbita...   if you'd like a different viewpoint. 0:00 Intro 1:41 Atomic orbitals recap with props! 2:22 Covalent bond reminder 3:08 Atomic orbitals don't work for C with more props 5:59 Hybridisation option 1 8:07 Why methane is tetrahedral 9:20 Overlapping molecular orbitals option 1 10:50 Hybridisation option 2 14:53 Overlapping molecular orbitals option 2 16:12 Why ethene is flat 16:35 Benzene is sp2 too 18:03 sigma and pi bond 20:07 Hybridisation option 3 21:45 Triple bond in alkynes 26:15 NileRed moment 26:26 Bonding and Antibonding orbitals 30:17 Colour terminology 32:24 How colour happens in molecules 37:10 How molecular structure affects colour 39:00 SQA questions on all this stuff?
