Correct IUPAC name of above compound is trans-$2$-chloro-$3$-iodo-$2-$pentene.
Correct IUPAC name of above compound is trans-$2$-chloro-$3$-iodo-$2-$pentene.
The parent hydrocarbon contains $5 C$ atom continuous chain with one $C = C$ bond between second and third carbon atom.
Hence, it is named as $2$-pentene.
One $Cl$ and one $I$ are present at second and third carbon atom respectively.
The molecule has trans geometry across $C = C$ bond.
Hence, it is named trans-$2$-chloro-$3$-iodo-$2$-pentene.
