Construct a simulated 1H NMR spectrum, including proton integrations, for CH3OC(CH2OCH3)3. Drag the appropriate splitting patterns to the approximate chemical shift positions; place the integration values in the small bins above the associated chemical shift. Splitting patterns and integrations may be used more than once, or not at all, as needed. Likewise, some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations.
PVA (polyvinyl alcohol) strands can form hydrogen bonds between different parts of the same strand. Illustrate how this can occur by using a sketch to show the hydrogen bonding.
