Question

onstruct a simulated 1H NMR spectrum, including proton integrations, for CH3CH2CO2CH2CH3. Drag the appropriate splitting patterns to the approximate chemical shift positions. Drag 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. Some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations. Note: Within a particular chemical shift zone, how do CH3 vs CH2 vs CH usually order?

Answer 1

For the last point

within a given range of chemical shift CH proton will have higher chemical shift because it is connected to more no of bonds, so more deshielded it will be. Then CH2 and then CH3.

So CH3 unit will have lowest chemical shift value then CH2 unit and CH will have highest value of that.
