Expert Solution

Step 1: Double bond equivalency
Given that, the molecular formula of the unknown compound is C5H10O.
The formula of the Double bond equivalency is
DBE = (No. of carbon atoms + 1) + () = (5+1)-(10/2) = (6-5) = 1.
So, the unknown compound has one unsaturation.
Also, given the IR analysis, the unknown compound has a keto group.
