The IUPAC name of the compound is 2-ethenyl cyclohexane carbonitrile.
Rule:
Terminal functional group ⇒ i.e carbon containing group (here nitrile group) ⇒ if directly attached to the ring ⇒ the ring is the main chain and the functional group is a substituent, therefore a special substituent suffix is used at the end (here f.g suffix is nitrile but if its treated as a substituent then the suffix is carbonitrile)
