    Cards (3)

    • integration value & splitting peak?
      no of H on the carbon. splitting pattern- no of protons attached to adjacent carbon
    • Si(CH3)4 and either CCl4 or CDCl3?

      act as standard- inert so don't react with sample. have no H so no peaks. CCl4 non polar-non-polar organic molecules CDCl3 polar covalent molecule - polar organic compounds. easy to remove low volatility and low bp.
    • Table B difficulty?
      H attached to both C-Cl and adjacent to C=O so doesn’t fit with data in table B
