MCQ
The $IUPAC$ name of the compound is


- ✓$trans-2-$ chloro $-3-$ iodo $-2-$ pentene
- B$cis-2-$ chloro $-3-$ iodo $-2-$ pentene
- C$trans -3-$ iodo $-4-$ chloro $-3-$ pentene
- D$cis-3-$ iodo $-4-$ chloro $-3-$ 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.
