Anewly isolated natural product was found to have the molecular formula c15h28o2. by hydrogenating a sample of the compound, it was determined to possess one π bond. how many rings are present in the compound?

one ring

Explanation:

C15H28O2: DU= (2(m)+2-n)/2

m is the no of Carbon atoms and n is no of Hs in the given Molecular Forumla.

DU=2(15)+2-28/2= 32-28/2=2

It mentioned that it has one double bond and it corresponds to one DU.

And remaining one DU corresponds to one ring

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
