Expert Solution

Step 1

As given Compound has molecular formula C₈H₁₈O.

There is one hetero atom Oxygen. Oxygen being more electronegative element has -I effect , so de-shielded the proton of carbon atom.

Strength of De-shielding is more for hydrogen of carbon atom that is directly attached to Oxygen, and less for the hydrogen of carbon atom that are at some distance.

Splitting Of H is given by n+1 rule, where n is the no of hydrogen atom on adjacent carbon atom
