This strategy is called D2O exchange or, more colloquially, the “D2O shake.” This exchange eliminates the OLH resonance (thus identifying it) and also eliminates any splitting between the a-protons and the OLH proton. The only splitting re- maining is then the splitting with any b-protons.

How do you replace H with D?
Due to the acidic nature of α hydrogens they can be exchanged with deuterium by reaction with D2O (heavy water). The process is accelerated by the addition of an acid or base; an excess of D2O is required. The end result is the complete exchange of all α hydrogens with deuterium.
What does d2 mean in organic chemistry?
Hydrogen-d2. Deuterium molecule. Hydrogen, isotope of mass 2.
How do you draw Lewis structures step by step?
Are Lewis structures hard?
In our example, carbon wants eight octet electrons and each of the four chlorine atoms also want eight octet electrons. The total number of octet electrons for the molecule will then be equal to 8 + (4 × 8) = 40. Figure 10.8 See, Lewis structures aren’t so hard, after all!
How do you draw a good Lewis structure?
- Step 1: Find the Total Number of Valence Electrons.
- Step 2: Find the Number of Electrons Needed to Make the Atoms “Happy”
- Step 3: Determine the Number of Bonds in the Molecule.
- Step 4: Choose a Central Atom.
- Step 5: Draw a Skeletal Structure.
- Step 6: Place Electrons Around Outside Atoms.
