Fenchone is a ketone found in oil of fennel. if fenchone has m+ = 152 and contains 1 double bond(s) and 2 ring(s); what is its molecular formula?
enter the formula in the form ch first, then all other atoms in alphabetical order; do not use subscripts.
the formula is case-sensitive.

C10H16O

Explanation:

Ketones are families of organic compounds with functional group of C=O, they have two organic radicals attached to the carbon atoms, hence ketones have a common formular RR'CO, where R and R' may be alkyl or aryl groups. The names of ketones alwas end in -one. Ketones or Alkanones are almost similar to Alkanals or Aldehydes.

From the question , the molecular weight of Fenchone is 152g/mol

The structural formula is as shown in the attachment
