ANSWER:Solution 15P
The Molecular ion peak of unknown compound is 86, which is an even mass number. So it contains Carbon, Hydrogen and Oxygen atoms only.
Know the molecular formula of unknown compound by using molecular mass peak as follows:
Calculate double bond equivalency as follows:
As per the statement of question, unknown compound is a ketone. So there is no chance for ring and double must be with oxygen. Thus, the possible ketones having molecular formula
