Nmr spectrum - Study guides, Class notes & Summaries

What is an alkene and its general formula? It is an unsaturated hydrocarbon with a least one C=C bond. General formula is CnH2n What is a sigma bond? σ single covalent bond formed when two s orbitals overlap. High electron density What is a pi bond? sideways overlap of p orbitals that occur in a double or triple bond. Much weaker than sigma, low bond enthalpy and lower electrostatic attraction Is an alkane or an alkene more reactive? Alkene. contains both sigma and pi bonds with high ele...

attachment 5 2 .docx Can you please provide me with at least a 5-page review writeup based on a sample of CBD oil I ran some NMR experiments on: 1H NMR, 13C NMR without decoupling, 13C NMR with decoupling and 1H-13C HSQC. Please add references and use other articles not just the two articles I provided – there may be better ones that can answer the 4 main goals I am trying to answer for. It's important to note that the assignment and interpretation of peaks in the 1H NMR, 13C NMR with...
